How does DNA paternity testing work?
DNA testing examines the genetic material that a child inherits from his/her biological parents. Samples (blood, buccal swabs, or other body tissue) are taken from the parties to be tested. From the sample, the childs genetic material is extracted and compared with the genetic material from the mother. The childs DNA characteristics that are not found in the mothers DNA material are inherited from the biological father. If the genetic material from the tested man does not share common characteristics with the childs genetic material, then the tested man is excluded as the biological father. If the DNA does contain those genetic characteristics, then the probability that the tested man is the true biological father is reported.
Simply put, DNA is a comparison between the child’s and parents’ genetic makeup. Everyone has a genetic code that was transmitted through the heredity chain to give them their own identity. When half of the child’s DNA is determined to match the mother and half matches the father, then paternity is established. If, for example, the father’s DNA does not match the child’s it is determined a “mismatch” and the alleged father is excluded. It is important to note that 30% of all paternity tests reveal exclusions. How The Collection Of The Sample Is Done A very easy 30-second swab of the mouth is all it takes. The procedure can be done in the privacy of your home for your convenience. Samples are taken from the mother, the father and the child and secured. The samples are then sent by Fed-Ex “over-nite express” to the world renowned laboratories of Chromosomal Labratories Inc. located in Phoenix Arizona for testing. It takes about three business days to receive the results.
DNA analysis, which is a major advance in the field of paternity testing, involves the direct examination of the genetic material that a child inherited from its biological parents. DNA is located throughout the human body and in the same identical form. Thus, DNA in blood is the same as that in skin, cheek lining, muscle, bone, teeth and various other tissues. The DNA a person has is fully established at conception and remains totally constant throughout life. During the paternity testing process, the genetic characteristics of the child are first compared to those of its mother. Those characteristics in the child that cannot be found in the mother have been inherited from the biological father. If the tested man (alleged father) does not have the genetic characteristics necessary to be the biological father of the child, he is excluded. If the tested man’s DNA does contain those genetic characteristics, then the probability that this man is the true biological father is calculated an
