The laboratory conducting your DNA paternity test will compare your child’s genetic profile to yours and to the alleged father’s. If the three profiles do not match on all loci (positions) of the child’s DNA, the child cannot be the biological child of the man tested. Also, the child’s profile will always match the mother’s profile on 50% of the loci. If the child’s profile matches the alleged father’s profile on 50% of the loci, the child cannot be the biological child of the man tested.
The laboratory will also calculate a “probability of paternity.” The probability of paternity is the percentage of times that the father’s DNA profile would match the child’s DNA profile if the father were the biological father of the child. The probability of paternity is not the same as the chance that the man tested is the biological father of the child.
The probability of paternity is usually calculated using the “product rule.” The product rule is a statistical method that takes into account the number of loci that match and the number of loci that do not match. The product rule is used to calculate the probability of paternity because it is the most accurate method available. The product rule is more accurate than other methods, such as the “rule of thumb” or the “counting method.”
A paternity test may be ordered if there is a legal question over who a child’s father is. For instance, if a mother is receiving child support from a man she believes to be the father of her child, she may want to order a paternity test to make sure he is the father. A paternity test may also be ordered if a child wants to know his or her father’s identity. Paternity tests are also used in cases of inheritance and immigration. The results of a paternity test are usually admissible as evidence in a court of law.
DNA paternity test: How it’s done
A paternity test is also called a “DNA paternity test.” It is generally considered to be the most accurate way to determine if a man is the biological father of a child. It is performed by collecting a sample of DNA from the child and the putative father and then testing the samples to see if they match. the accuracy of a DNA paternity test samples are usually collected by swabbing the inside of the cheek with a cotton swab. The swab is then sent to a laboratory for analysis. The results of the test are usually available within a few days to a few weeks.
