IIRC, sand is made up of fragments of crustaceans and cartilages and bones and stuff (the scientific word “stuff”). It is those fragments that allow an expert to trace it to a specific location.
But from whom are the 1.75 million DNA profiles? I suppose they are not all criminals. Also, with what method are they comparing them? In other words I think they are saying the DNA doesn’t match, as none of those 1.75 million are the perpetrator. But what if someone in there was distantly...
The Y match would be a piece of the puzzle though. If they did SNP testing, that is what would be used for tracing current (recent generations) lineage. I don’t believe they do that in Japan, due to regulations. However, if the perpetrator were American, which is one working theory, that could...
I can, to some degree. Only men get the Y chromosome; women do not have one. This means, like you stated, it is passed down from male to male only. In forensic investigative genetic genealogy, a Y match helps to identify a perpetrator of a crime or unidentified human remains. Getting a match on...
Wow. You know what hit me while looking at the front of the house? Rei’s room and the bathroom are on the part of the house that shared the wall with next door. Rei was likely killed silently. It makes it so much more understandable Ann Irie and Haruko didn’t hear anything.
It would be very, very bad practice to not test autosomal dna prior to anything else. Moreover, Japan limits the testing of snp testing dna. What I wonder is if they ran anything through CODIS.
