Somalis have strong genes, they look like light-skinned Somalis.
Some of them could be 25% Somali or 75% Somali. They likely aren't all exactly half Somali.
Maybe a few full Italian or full Somali visitors as well.
I think that woman is half and the child is a quadroon.
They all look somali but some look so italian! at @0:22, the woman and the girl. The woman looks italian but tanned. Nothing Somali to me!
