The only thing I can see that these places might have in common is possibly ancient genomes? I don’t know, but its interesting and all of them are this subtype allele HLA A 02 01. The list starts with the highest percentages of this allele and are higher than percentages of rh-‘s. Mexico Sonora, USA Arizona Prima, Finland, Bulgaria, Spain Catalonia, Portugal North, Ireland, USA Caucasian, Spain Basque, Australia, Turkey, China Tibet, Native Americans, Morocco Berber, Uganda, Japan, South Chinese Han, and many others.

If you scroll down to the chart referring to “allele HLA A 02 01”, it includes the following: It says its common globally but has some rare subtypes. I’ve been wondering if there was a connection somewhere and then I saw this on Wikipedia, referring to HLA A 02(major histocompatibility complex). I read an article about a monk having low hemoglobin levels, which is something rh-‘s have also. And also the Tibetan monks inheriting a Denisovan gene that allows them to live in high altitude. Does anyone remember the study on the Han Chinese blood types? Some of them were different kind of O-‘s and they are normally B+ I think.
