How To Beat A DNA Paternity Test

Do you think you know how to beat a DNA paternity test? Well some people have given advice on how to beat a paternity test, but in all reality, you cannot alter your DNA. You can try drugs, food, water intake, medications and alcohol, but the results will remain the same, if you are a parent, it will show up in the genetic DNA paternity testing procedure.

We can find the latest story about Anna Nicole Smith and her child?s paternity quiet the opposite of someone thinking they can beat a paternity test. The alleged fathers are actually fighting over who is the father. They all want to be the father. If they would consider how to beat a DNA paternity test, they would find the same answer; there is no way to beat a paternity test.

When a mother or father decides on a paternity test, you find many online websites offering free kits and then you send the samples in for testing. Now if the mother, father and child are not all present for this sample collection, some might think about substituting somebody else?s DNA in place of their own. This is why the legal system requires the individuals to go to a local laboratory or hospital to have samples taken.

In a Michigan court case a while back, a man who thought he was the father of the child for years, paid child support and later petitioned the court to stop payments and have a paternity test because the child told him that another man was his father. The court declined his request during the divorce proceeding. In this case, the biological father had help from the court on how to beat a paternity test because the man was already paying support for the child and was named the father. In this absurd case, the custody of the child changed from the mother to the real father and the man had to continue to pay child support to this father to support the child after the biological father had full custody.

Here are three ways for the biological on how to beat a paternity test. If the alleged father, not yourself the real father, has bad legal counsel, poor laboratory DNA procedures and the old stand by, the default judgment. Most alleged fathers just do not show up for court and are deemed the father whether they are or not. This is the default judgment that occurs more than one would think. If you feel you might not be the father or even if you are, you should always have a paternity test to find the truth before you pay for it for at least eighteen years.

How Accurate are DNA Paternity Test Results

One question on many people?s minds when they look into paternity testing is how accurate the paternity test results are. No test can ever be 100% accurate but how accurate can you expect your paternity test results to be and what should you expect from a DNA testing lab?

There are two results involved in a paternity test, the first is called exclusion. Exclusive paternity test results exclude a man from being a father of a child. This means that in the paternity test the DNA of the father did not sufficiently correspond to the DNA of the child to consider him as a prospective father. In this case the result should be 100% accurate, if a man is excluded from being a child?s father there should be no way he could possibly be.

Inclusive paternity test results however are different, they refer to the likelihood that someone is the father of the child. Although no test can ever be 100% certain most paternity test results should prove at least 99%, preferably closer to 99.99% that a child is the father.

The accuracy of paternity test results depends on how many loci (or points) are tested on the DNA segments of the alleged father and child; the higher the number of loci, the greater the accuracy that can be obtained.

To get the best results from your paternity test you should choose a laboratory that tests at least 13-16 loci and that excludes fathers who show a difference in two or more DNA patterns on the loci (this is the AABB standard that is used in accredited DNA testing labs).

In conclusion, although paternity test results can never be 100% accurate you should look for at least 99% accuracy and preferably closer to 99.99%. Accuracy is obtained through testing a larger number of loci and good DNA testing labs usually test about 16.

Should You Have A Gender DNA Test For Your Unborn Child

A gender DNA test can reveal the gender of the fetus as well as showing paternity and genetic makeup. The procedure has been used because many feel it is a safer method than an amniocentesis as well as a CVS. This procedure is noninvasive where as an amniocentesis is invasive and can have risks, including inducing labor, fetal injury and in some cases termination of the pregnancy.

The gender DNA test requires taking blood from the mother who has fetal cells in her bloodstream. They isolate the Fetal DNA and will then determine the gender of the fetus. This is possible because the mother?s bloodstream carries fetal DNA from the placenta throughout the body. In most cases, a laboratory technician and not a doctor do the taking of the blood and testing. Performing the test as early as ten weeks after conception tells the gender of the fetus, although some tests may show accurate results as early as six weeks.

There are many companies around today that offer kits by way of mail, for a do it yourself home test, which you then send the sample to their lab and have the blood sample tested. Are these companies legitimate? In most cases they are, although they all charge different prices for the test kits and the testing procedure.

The question, should you have a gender DNA test is so controversial because, it takes the thrill and joy away from the birth, which most women know through experience is the beautiful part of birth, the rest can be painful. Some people may decide to end a pregnancy if the gender turns out to be wrong for what they are hoping for at the time. This type of gender DNA testing is wrong. Terminating a healthy pregnancy because the gender is not what you want leaves many religious groups and abortion groups positively outraged.

The right to select the gender of your baby may at some point unbalance the creation of life because some cultures and some people prefer boys rather than girls. This will cause less female populations and could result in the distinction of an entire heritage. Asian cultures are top on this list as they do end the life of baby girls. This way of life will eventually delete the Asian population.

With all the information about the gender DNA test and what could result if people use it for gender selection, this topic will remain a hot issue in the future. Religious groups believe that the sex of your baby is God?s will and will never change the way they believe. Abortion groups will continue to oppose this testing procedure if it is used for gender selection. I personally was happy to wait until my baby was born to find out the sex, and today I have a boy and a girl who have grown up and live wonderful lives.

Mitochondrial DNA Testing Also Known As Maternal DNA Explained

 

Mitochondrial DNA testing is a type of genetic testing which is used to find out more about the mother?s side of the family as mitochondrial DNA (also known as maternal DNA) is passed from the mother to her children. In this article we are going to look at how mitochondrial DNA testing is done, what it is used for and the differences to nuclear DNA testing.

Mitochondrial DNA is DNA found in the mitochondria of the cells and is different to the nuclear DNA. The nuclear DNA is a mix of the mother and father?s DNA, whereas mitochondrial DNA is only inherited from the mother. When the egg from the mother and the sperm from the father join to form the new baby the tail of the sperm which contains the father?s mitochondrial DNA is left behind and so only the mother?s mitochondrial DNA is passed onto the child.

Like nuclear DNA tests mitochondrial DNA testing is done by first collecting a sample of DNA either through a blood sample or through a cheek swab, the cheek swab being the preferred method used. These samples are then sent away to laboratories that do mitochondrial DNA testing and they in turn analyze the results.

Mitochondrial DNA testing is used for a number of reasons ? the first is to establish a direct family link on the mother?s side of the family, it can also be used in ancestry DNA testing to test the mother?s ancestry or in forensic DNA testing.

In the 1980?s Dr Mary Claire King also started using mitochondrial DNA testing to solve cases where the parents of a child are unknown. She used a section on the mitochondrial DNA that varied substantially and so provided evidence of who the mother or grandmother was. Due to the fact that mitochondrial DNA is passed directly from mother to child through the generations, maternal aunts and uncles should also contain mitochondrial DNA matching that of a child with missing parents and so if the maternal grandmother cannot be found it is possible to try matching the child with an aunt or uncle.

In conclusion mitochondrial DNA testing involves the testing of mitochondrial DNA which is passed on from mother to child through the generations and so may be used both to match a child with its maternal grandmother, aunt or uncles if the mother is missing but also can be used in ancestry DNA testing of the maternal side.

The Uses of Genetic DNA Testing

Genetic testing or DNA testing is a relatively recent development due to advances in scientific knowledge that has many and varied uses including paternity testing, testing for various genetic diseases during pregnancy, or for forensic investigations. In this article we are going to be discussing some of the uses of genetic testing and how they work.

The first use of genetic testing is called paternity testing and is used to verify who the biological father of a child is. When there is a doubt about who the biological father of a child is this can hold not only implications for the relationship both between the parents and between the father and child; but also legal and financial implications (for example, who is responsible for meeting the child?s financial needs as they grow up). Genetic testing in this instance can be done through collecting a sample of the father?s, mother?s and child?s DNA which are then compared at various points. This method of verifying paternity is a lot more accurate than older methods and is also painless as a DNA sample can be collected from a swab of the cheek.

Another use of genetic testing is to help create your family tree and verify family history. In this case parts of the Y chromosome that don?t tend to change down through the generations will be compared to others. People who have a common ancestor will show similar characteristics in certain places of this specific chromosome and so will help establish ancestral lines.

This is also related to genetic testing for ancestry, or what percentage of each race group you have in your DNA. By doing an ancestral genetic test through laboratories that offer this service or home packs to test your ancestry you are able to determine your race history. There is a story, for example, of a man who thought he was African American most of his life, only to discover that he had no African American blood in him but a mixture of other race groups including Indo-European and Native American.

Prenatal genetic testing may also be used to discover a number of diseases or health problems before a child is born. Many diseases may be related to an abnormality in the DNA which can be discovered through DNA testing in order to warn the parents of this possibility so that they can do what is best for their child.

There are a number of uses for genetic testing and the above are just a couple of uses for personal genetic testing including paternity testing, genetic genealogy, ancestry testing and testing for possible health problems in an unborn child. Genetic testing is generally non-invasive and painless as DNA swabs can be taken from the cheek for comparison instead of having to take blood. These DNA swabs are then analyzed in a laboratory to compare different DNA segments and so determine the results of the above tests.

Maury Made a Living on DNA Testing

Do you watch daytime television? If you do, then you know that it is horrible. You have to put up with soap operas, court shows, and a plethora of talk shows when you watch television during the day. The funny thing is that many of us still watch daytime shows, even if they are terrible. These shows have been around for years and don?t seem to be going anywhere any time soon.

Talk shows have to be the most unsettling shows that are on the daytime category. I observed that the producers of talk shows only seem to have a handful of show topics. They recycle and regurgitate these topics over and over again. Among these recurring shows, the DNA testing show is probably the most overdone show.

You will often see some poor woman getting berated by an audience of strangers because she is there for some free DNA testing, when you turn on your television during the day. I have seen this show so many times that it makes me sick. A woman who has no idea the identity of her baby?s father can turn on the Maury show to help her figure that mystery out. Since DNA testing can be very expensive, single moms may not be able to afford it.

To be honest, I am equally enthralled and entertained as much as I am disgusted by the DNA testing shows. In my opinion, this is the human comedy/tragedy at its best. There are two people that once were close, and now they cannot stand each other if only for a night. There is also the father that decided that he no longer wanted the responsibility and so he began to deny fathering his children.

It can be hard to watch the ever-popular DNA testing talk shows because there is a lot of pain, frustration, anxiety, and emotion involved. The bottom line is that there is a child that needs to be taken care of in the midst of all this. The focus should be on the child and not on whether or not the child?s parents are standup, responsible people. It?s a sure bet that something went terribly wrong if someone is caught in a situation that requires DNA testing.

Accuracy of DNA Paternity Testing Methods

There are two main methods which can be used for paternity DNA testing, namely, PCR (Polymerase Chain Reaction) and RFLP (Restriction Fragment Length Polymorphism). In this article we are going to be looking at these two methods, what the difference is and how they work.

Polymerase Chain Reaction testing usually involves taking a swab from the inner cheek for DNA samples. It is a faster test than RFLP and usually looks at between six and nine loci on the DNA. This test however does not provide the same degree of information as is provided by the RFLP test.

PCR DNA testing works by ?amplifying? the sample DNA, or taking a small sample of DNA and then multiplying it. This is useful if only a small sample can be obtained and is also useful for working with degraded DNA. When using PCR DNA testing however the laboratory needs to be particularly careful about preventing contamination within the sample as the amplification process could tend to increase the chances of contamination.

The process of PCR DNA testing involves heating the DNA, adding primers and then cooling it so that it recombines and an enzyme reads the DNA sequence in order to create multiple copies of the DNA.

The Restriction Fragment Length Polymorphism test takes longer than the PCR test and is a slightly older method but can provide more reliable results as each loci presents more information regarding paternity. It requires a larger sample of DNA and is more likely to use blood for the DNA testing but it can also be done using a swab from the inner cheek if necessary.

The AABB report from 2004 stated that there is a decrease in the number of laboratories using the RFLP method and an increase in laboratories using the PCR method of DNA testing with PCR being used in 98.34% of the cases.

In conclusion, there are two main methods of paternity DNA testing that are mainly used today. These two methods are Polymerase Chain Reaction testing and Restriction Fragment Length Polymorphism testing. PCR testing is used in 98.34% of the DNA testing cases according to the 2004 AABB report and seems to be increasing over the older method of RFLP. PCR is a quicker method of testing and multiplies the amount of DNA material so that only small samples are needed; however this does lead to a risk of contamination. If you are going for PCR testing or ordering a DNA home test kit you should ensure that they are AABB approved and that they offer at least a 99% guarantee and test at least ten loci.
