Q1: Anyone else out there of Haplogroup J2b1a (mutation 16278T in HVR1)?
Q2: mutation 8839R - Is it a gene recombination when the mutation is letter R (rather than T, C, G, or A), and is a gene recombination the same thing as cross-over meiosis? (Is chromosomal crossing over also known as recombination?) Does recombination only occur when one inherits the exact same marker from both mt and Y and the markers match up at the same location and thereby cross over? Please, if anyone can explain it to me I'd be greatfull. Wish I was a geneticist to understand it all.
I have my full mt-DNA genomic sequence for HVR1, HVR2, & CR. If anyone wants to compare, just email me direct at: marmel at pctcnet.net If we match we had a common ancestor about 12 generations back. I think I remember reading that matches with Family Finder have a common ancestor about 6 generations back (GGGGgrandparents). I have not paid for Family Finder yet. Waiting to see what develops next in the DNA genealogy field.
