testing of parents is the use of DNA to determine if two people have a biological parent-child relationship. A paternity test the DNA evidence establishes whether a man is the biological father of a person and a maternity test determines whether a woman is the biological mother of a person. Although genetic testing is the standard the more reliable methods are available, including ABO blood group typing, analysis of various other proteins and enzymes, or by HLA antigens. The current technique for testing the paternal uses polymerase chain reaction (PCR) and restriction fragment length polymorphism.
The DNA test is currently the most advanced technology and precise for determining parentage. In kinship DNA testing, the probability of paternity [1] is 0% when the alleged father is not biologically related to the child and the probability of paternity is generally higher than 99.9% when the alleged parent is biologically related child.
The DNA of an individual is almost exactly the same in every somatic (non reproductive) cells. Sexual reproduction brings the DNA of two parents randomly to create a unique combination of genetic material into a new cell, so that genetic material from an individual's genetic material from both parents in roughly equal quantities . This genetic material is known as the nuclear genome of the individual, because it exists in the nucleus.
By comparing the DNA sequence from one person to another person who can show if one of them is derived from the other or not. Specific sequences are usually looked to see if they have been copied verbatim from the genome of one individual to another. If this were the case, then it follows that an individual's genetic material could have been derived from that of another (ie, the parent of another). Besides the nuclear DNA in the nucleus, mitochondria in cells have their own genetic material called mitochondrial genome. Mitochondrial DNA comes only from the mother, without any mixture.
