Module 8 :: mtDNA & Y-STR
Topic 4 :: Y-STR Laboratory Analysis
Y-STR Profiles
It is important to note that, unlike the situation with autosomal STRs, it is not possible to distinguish fathers, sons, and brothers because, barring rare mutations, they all possess the same Y-STR profile. Some laboratories will emphasize this by including a statement to that effect in their reports.
