So my understanding is that Sub Saharans are from the Sub Saharan region that are distinct by being much larger than normal. Bigger, longer, and with larger heads. I don't have proof. But I have 3 animals fit this description and might be this type. One is a 5' 6" male that I've seen reach 3600g but is currently recovering from breeding fast and is at about 3000g.
I also have a female of the same length that is 3200g and looks thin. LOL! 3 of my hold backs are from her. And one of the females is the largest of the hold backs even though others share her appetite.
Have Sub Saharan been proven genetically?
