Parentage Testing

In determining family relationships, paternity is confirmed by testing 9 to 12 genetic locations of the mother, father and child. By comparing the DNA profiles of the mother and child it is possible to identify the alleles that the child inherited from the biological mother. When these alleles are excluded, the remaining alleles must have come from the biological father. If the DNA profile from the tested man is found to contain these remaining alleles, then a statistical analysis can be performed to determine the probability of this man being the father of the child.

In the DNA typing process, a DNA banding pattern or profile of an individual is first obtained from a tissue sample. The DNA profile is observed in the form of a set of DNA bands known as ‘alleles’. Each person has a maximum of two specific alleles for a given genetic location. This DNA profile is compared with the profile
