YSTR limitations
This is only an interim answer, but it seems to me that there are two contributors to the DNA in the present analysis of the Y chromosome. One of them could be Raffaele, and one is an unidentified individual. One problem with YSTR DNA profiling is that one cannot calculate a random match probability the way one does for autosomal DNA profiling. It is not as discriminating, in other words. I will let you know as I learn more.
Rolfe,What I meant to say was, somebody please save me from looking this up, but are they only talking about Raffaele's Y-chromosome haplotype being possibly on that bra catch?
How many distinct y-chromosome haplotypes are there anyway? Is this any better than saying there was type A-positive blood at the scene and the suspect is A-positive?
