Hi
My first post here. I've been the admin for a one name project [RID(E)OUT] for some time now; my members ask questions from time to time and I do my best to help them but I'm stumped with this one... can you help please?
I have three members who, on paper, descend from three different sons of 'John' (b. 1745)... the men are five or six generations down from 'John' - two have identical sequences (37 markers), one has 1 fast mutation [DYS458].
Now, a fourth man has joined the project; on paper, he believes himself to descend from a fourth son of 'John' yet, in just seven generations to the CMA, his line shows 3 mutations [DYS460, DYS464c, DYS576] all of which are, I believe, 'fast' - but is this number feasible over so few generations? Is it more likely that the man actually belongs elsewhere on the tree - or is this rate of mutation ever observed?
Cheers, Karen
