My husband Dave Murphy is R1b1a2a1a1b4b - L-21 - Kit #201315 at ftDNA, I administer his kit and have had his markers tested to 111 and had his autosomal (FF) done also.  What is the USA cost of Chromo2? What is it and where do you get it??  I myself have done my own Geno2 with National Geographic... is it the same thing???   I am having to finance these tests, so I am cautious what I have to order, would it be just as good to order DF85 at $39.00 ?   My next question is his Y-DNA never quite matches exactly other Murphy's markers... off usually 1 marker or so. I am wondering if it is because he also has another Murphy 2nd great grandfather also born in Ireland. Could this throw his markers off a bit??  Helen Helen Nichols Murphy (Battleson), [email protected] - Coronado, California
