I don't recall seeing specifics on this very interesting block that you (a
Norwegian) share with a Mongol and a Pima. How large is this segment, and
at what position on the X?
There has been a lot of discussion lately about 5 Mb segments seen in
uploads from 23andMe to Decodeme between Europeans and people from almost
everywhere outside of Sub - Saharan Africa (when comparing to the 52
reference individuals from the HGDP-CEPH panel). I don't recall anyone
mentioning segments as large as 10 Mb though.
