Two excellent books on the subject: Adam's Curse The Seven Daughters of Eve by Bryan Sykes Mbmackie123@cs.com wrote: No. Women do not have Y choromosomes and cannot be traced back to a specific ancestor. Whereas a man can be traced back, if he knows (or thinks he knows) who his ancestor is. By comparing his Y-DNA with other males who claim same ancestor, he can either prove or disprove. Women have a much broader base...and can be traced only to their common heritage...i.e. ethnic background, etc. Well, those who know more about this than I can chime in here. :-) Frank Ross, University Place, Washington, USA EAA Chapter 35, San Geronimo, TX photo album at: http://photos.yahoo.com/alamokr2 __________________________________________________ Do You Yahoo!?
