DNA Paternity Testing Dallas, TX

DNA testing is sometimes referred to as DNA fingerprinting. It is called a fingerprint because it is very unlikely that any 2 people would have exactly the same DNA information, in the same way that is is very unlikely that any 2 people would have exactly the same physical fingerprint. The one exception to that would be with identical twins, or monozygotic twins. When one egg is fertilized by one sperm cell, and then divides and separates, two identical cells will result. Monozygotic twins are genetically identical (unless there has been a mutation during development) and they are almost always the same sex.

Only a small sample of cells is needed for DNA fingerprinting. DNA testing can be done on cells obtained by a simple swab of the cheeks inside the mouth, a drop of blood, root of hair, or semen. The process of collecting these specimens is a very simple process, but if not done properly can lead to inconclusive results. Although home paternity test kits are available, they are not as accurate and the results cannot be used in a court of law.

In the United States, AABB regulates DNA paternity and family relationship testing industry. Only the DNA test results produced by an AABB-accredited laboratory are legally admissible and accepted by government child support agencies, welfare benefits offices and immigration authorities. The DNA paternity test that follows strict chain of custody can generate legally admissible results that are used for child support, inheritance, social welfare benefits, immigration, or adoption purposes. To satisfy the chain-of-custody legal requirements, all tested parties have to be properly identified and their specimens collected by a third party professional who is not related to any of the tested parties and has no interest in the outcome of the test.

 DNA testing is currently the most advanced and accurate technology to determine parentage. In a DNA parentage test, the probability is 0% when the alleged parent is not biologically related to the child and the probability typically greater than 99.9% when the alleged parent is biologically related to the child.

 Genetic testing used to determine the biological father of a child is called a DNA Paternity test. Every person carries two copies of most genes (one copy from the mother and one from the father). DNA testing is a a test to identify and evaluate the genetic information called DNA (deoxyribonucleic acid) in a person’s cell.

It seems most famous men have at least one love child. Rock stars and professional athletes are notorious for multiple illegitimate children from multiple mothers. Retired Houston Rockets point guard Calvin Murphy has 14 kids by 9 different women, and John Edwards is recently in news and maybe taking a DNA paternity test soon.

It seems every year a new teen wannabe star makes waves in Hollywood and sports the last name of a D list celebrity. Many times they changed their last name prior to moving to Hollywood to their father’s more recognizable last name. I have to admit it is more of a conversation starter.

Omer Bhatti and Michael Jackson

What about Michael Jackson? It is only a matter of time before Billie Jean comes forward. Have you heard about Omar Bhatti? There are rumors he is Michael’s love child. I have to admit this guy has a striking resemblance to the King of Pop.

Bill Clinton supposedly has a son in 1984 with mistress Bobby Anne Williams. The story as told by an Arkansas State Trooper goes like this… He drove Gov. Clinton and two black women to a sex orgy near Hot Springs Arkansas at Gov. Clinton’s mother’s house. His mother was out-of-town. A year later little Danny was born to one of the women. A lie detector test in 1997 on Bobby Anne Williams indicated that she wasn’t lying and that Bill Clinton was the genetic father of Danny.

Danny and Clinton

Mel Gibson has a love child as well. According to the child Mel and her mother were together 30 years ago, way before Mel became famous. Mel Gibson denies that he is the father. It is unknown whether he would take or has ever taken a DNA paternity test.

The list of illegitimate children to famous people could go on and on. Statistics show there is a direct correlation between fame, fortune and having a love child. My personal research indicates that the number of illegitimate children actually decreases as fame increases, and 1.7 is the magic number of illegitimate children to have. Using complex math, algorithms and circular logic I have come to the conclusion that a struggling actor or starving musician should father a love child or two to ensure a famous and prosperous career. However, fathering more than two illegitimate children has shown to be as detrimental as having no illegitimate children at all. Confirming the genetic paternity of a love child with a DNA test is inconclusive.

Believe it or not DNA tests are not as accurate as they claim to be.  Chimerism is defined as one individual having two completely different sets of DNA.  How common chirmerism occurs is completely unknown and statistics quoted in textbooks or on websites are completely fictitious.

DNA Chimera Rape

An episode Maury Povich the other day completely humiliated a young woman who was 100% sure this particular man was the father of her child.  After 30 minutes of yelling, stories, pointing fingers and drama the DNA proved that there was a 99.9% chance he was not the father of the child.  The young woman stared at the floor in shame.  The next lady on Maury was having the fourth man tested and the DNA test proved he wasn’t the father either.  This TV show led me to write this article on chimera and how misleading a DNA test can be. 

How is it possible for one person to carry two sets of completely different DNA?

Although many say that it is rare the truth is we have no clue how often it happens.  With so many couples taking fertility drugs it is probably more common.  When a sperm fertilizes an egg the cells start multiplying and the cluster of cells is called a zygote.  If a woman produces more than one egg and both get fertilized than more than one zygote is formed and the woman may eventually have twins, triplets, etc.  I say “may” because if two zygotes merge than the child formed is called a chimera.  The appearance of a chimera is identical to a normal child.  When the zygotes merged they begin to act as one and start making organs and body parts.  The result is an individual who is a genetic mosaic of body parts. 

There are documented rape cases of men whose semen did not match their DNA.

Our court system puts a great weight on DNA evidence.  The other day I watched a local Dallas news station report how DNA evidence led to the release of a man who had served 8 years of his prison sentence for rape. 

Recently there was an episode of CSI where a man was raping women without a condom or a mask covering his face.  They put him in a line up and he was picked by the woman whom he had raped. They tested his DNA and it did not match the rape kit so they let him go. The DNA was close but no match so they interviewed his brothers and it was none of them either. Eventually the lead CSI, Grissom saw the lines on the guys back like in that picture and he took a blood sample which matched the rape kit. Turned out his sperm did not have the same DNA as his blood and skin.
