BlueGiant Posted July 16, 2007 Share Posted July 16, 2007 Well, if there was a Y-chromosome genetic marker, then women could not, at least genetically, be Jewish. Cue potential tangent: There are, in fact, some genetic disorders more common to a particular Jewish line of descent (can't remember the name), called Tay-Sachs. This kind of became amplified due to the fact that it was a small, intrabreeding population. Same sort of thing shows up among the Amish (certain orthopedic disorders), and I've heard that the Salt Lake City genetic clinic gets rather interesting. There are some genetic components, but they, frankly, are due to inbreeding, from either historical location reasons or, later due to groups trying to keep their own bloodline "pure." Really, all that is needed for a genetic marker to develop is a small-ish, inbred population. Gotta love the mechanisms behind natural selection.
