Qabil endogamy among Somalis is kinda overblown even in the homeland. Ask most people to recount the qabil of all their grandparents and you'll notice the women were often of different qabils and subqabils. Like me. I'm mostly Darood and yet my direct maternal line is Raxanweyn (Maalin Weyn):
Notice how the maternal lines are all different with two being of totally different qabils. I noticed I'm not unique in this either. Alotta people running around with ayeeyos and great ayeeyos from different qabils and subqabils or their hooyo is from a different qabil or subqabil from their dad. Somali mtDNA diversity correlates well with this too. I've seen samples from all over Somaliweyn and everywhere you go you see the same overall mtDNA lineages popping up.
It's even in a lot of the qabil origin myths. The Darood's origin myth is seriously about how they were formed through Sheikh Darood marying
Dobira, the Dir clan chieftain's daughter. We have always been intermarrying on the maternal side which explains the general autosomal homogeneity and high
IBD sharing among Somalis despite the disconnect in terms of Y-DNA like T-L208 Vs. E-V32 or some niggas so far seeming to have V32 subclades separated by many centuries.
