The DNA thing patterns are where I get confused also... but anyway,
he's tracking patterns on the y chromosome. Women don't have a y
chromosome. He says that men give their y chromosome to their sons
in a relatively intact state. So that enables him to track patterns
on the y chromosome.
woman: xx
man: xy
The "adam" thing weirds me out, it's too biblical. I guess they are
trying to make it accessible for us when they use those terms...
I do wish they had explained the DNA pattern thing a bit better on the show.
