While waiting for my Full Y Gemome results I’m keeping my mind occupied by playing around with Z36 STRs. I took all the Z36 surnames and searched the projects to get as accurate a haplotype for each surname as possible. I then combined the close clusters (i.e. Musselman/Binkley/Singer; Erskine/White/Stuart/Tyson; and Brandeberry/Barthelmus) to count as only one haplotype for each. This gave me 56 Haplotypes for Y-12; 55 for Y-25; 54 for Y-37; 48 for Y-67; and 11 for Y-111. While tabulating a Z36 Modal haplotype I noticed this anomaly:

R1b frequency for DYS 437 http://freepages.genealogy.rootsweb....logy/yfreq.htm

14-12%; 15-85%; 16-3%

Z36 frequency for DYS437

14-42%; 15-53%; 16-5%

R1b frequency for H4

http://freepages.genealogy.rootsweb....logy/yfreq.htm

10-20%; 11-71%; 12-9%

Z36 frequency for H4

10-48%; 11-50%; 12-2%

The modal for both holds, but just barely. But here’s the weird thing. You would expect the DYS437=15/H4=11 group to be the largest, since that is the modal. But it isn’t even close. This is how it breaks down:

DYS437=15 & H4=10 21 of 54 or 39%

DYS437=14 & H4=11 19 of 54 or 35%

DYS437=15 & H4=11 8 of 54 or 15%

DYS437=16 & H4=10 3 of 54 or 6%

DYS437=14 & H4=10 2 of 54 or 4%

DYS437=14 & H4=12 1 0f 54 or 2%

The off-modal DYS437 holds the H4 modal and the off-modal H4 holds the DYS437 modal.

Wow! After typing that last sentence I thought to myself “What’s so strange about that?”

Maybe this is just evidence of two early mutations under Z36; DYS437=15>14 and H4=11>10.

Thoughts?
