Majority of reer waqooyi from Bari/Mudug Puntland/Galmudug, all of SL,Dijbouti and majority Ethio Somalis are primarily Cushitic + minor Arab ( with some having other Horner admixes like Afars,Hararis or Oromos).In the South you tend to see non-Afro-Asiatic ancestry admixture like Indian (Cadcads) or Bantu (Bajuni or the Mushunguli speakers)How many times do you say ridiculous things? On average those from the Northwest and Northeast are more Somali than Southerners from what I've seen. Almost all the questionable results I see come from konfuur. And you are questioning the make up of Northerners. Do not throw stones in a glass house. You live closer to Bantus than they do to Nilotes.
