We all inherit our DNA from our biological parents â half from our mother and half from our father. A DNA paternity test compares a childâs DNA pattern with that of the assumed father to determine if there is a match.
Paternity testing done by profiling requires samples of the purported father and the child (that is, the presumed offspring). The mother's DNA is not necessary, but can be helpful. In this case, a sample from each person can be profiled and the profiles compared visually or electronically.Alternatively, the samples can be tagged with two different fluorescent markers, mixed and analyzed--looking for similarities and differences.xamining as few as 16 different locations in human DNA can yield very clear information on whether or not a DNA sample belongs to person A. This is how DNA analysis is used in forensic profiling. This is also what is now commonly referred to as a DNA fingerprint.
