What is a DNA paternity test, and how is it performed?

0

A DNA paternity test uses DNA samples from the alleged father, child, and mother to create their genetic profiles—snapshots of each person’s genetic makeup. Since children inherit their DNA from their biological mother and father, the child’s genetic profile should be composed of equal portions from the genetic profiles of the mother and father. In a DNA test, buccal swabs are used to collect DNA from loose cheek cells. DNA is extracted from these cells and purified for the Polymerase Chain Reaction (PCR). PCR targets specific segments in the DNA (called markers), amplifying them to detectable levels. The markers are recorded as a genetic profile. Statistical calculations are used to determine the probability of paternity based on how closely the child’s profile matches those of the parents.
