About this talk
Part of the nuclear DNA that is paternally inherited or passed down from father to son is found on the Y chromosome. Similar to mitochondrial DNA, Y-chromosome testing can be used to distinguish between individuals with different paternal lineages. Short tandem repeats (STR) on Y chromosome are called Y-STRs. Y-STR testing is identical to analyses of nuclear autosomal STR loci. Testing for this type of DNA is particularly useful when mixtures of male DNA (a minor male contributor) and female DNA (predominant female contributor) are suspected or only distant paternal relatives are available for comparisons. The presentation will introduce audience to Y-STR testing with a particular focus on the probative value of Y-STR DNA test reports.
