I'm not certain I understand you, Bob. What is a "pretty close mirror" at 37? Demes 2 and 3? Depending on how you count CDYa/b, which is prone to multi-step mutations, the genetic distance between Deme 2 and Deme 3 is *at least* 13 at 37 markers, which is a decided non-match. http://www.familytreedna.com/genetic-distance-markers.aspx?testtype=37 Diana > -----Original Message----- > From: y-dna-projects-bounces@rootsweb.com [mailto:y-dna-projects- > bounces@rootsweb.com] On Behalf Of Bob May > Sent: Thursday, August 12, 2010 3:36 AM > To: y-dna-projects@rootsweb.com > Subject: Re: [Y-DNA-projects] WAMH vis-a-vis CMA > > Interesting run down > at 12 Deme 1, 2 very closly related 3 fairly closley 4 not related at 25 dem1 moves > away and 2, 3 start to shift at 37 the 4 group are split apart demem 1 still close > Deme 2 failrly close at 37 still a pretty close miror of 37 > > bob > ----- Original Message ----- > From: "Diana Gale Matthiesen" <DianaGM@dgmweb.net> > To: <y-dna-projects@rootsweb.com> > Sent: Thursday, August 12, 2010 4:51 PM > Subject: Re: [Y-DNA-projects] WAMH vis-a-vis CMA > > > > > > You don't say how many markers, but an 11/12 match means very little. > > Even a > > 12/12 match means very little if you're talking about the WAMH.
