Hey, have you seen so far Somalis that are Somali 100% both on the genome level and haplogroups?Or that are least 100% from the Horn?
Haplogroups don't really say ANYTHING about what you look like. You cannot physically tell the difference between people from the
same ethnicity who carry different haplogroups. This is a newb mistake people always make when they just learn about haplogroups. For example, Greek people with haplogroup R, J, E, T, G etc, there is no way you can tell them apart as they have the same autosomal ancestry.
The main thing that affects your looks is autosomal ancestry (the other 22 chromosomes) and Somalis are mostly similar on this.
