Paternity testing using Y-STR haplotypes: assigning a probability for paternity in cases of mutations.
In parentage testing with male children, Y-chromosomal STR evidence is gaining more and more importance. In some cases, multilocus haplotypes of related persons can differ at a single locus due to a mutation. In this work, a likelihood approach is presented for the calculation of a probability for paternity under consideration of a single mutation event on the Y-chromosome. The new methodology is applied to two case examples.
