We are all identical, aren’t we? Yes, we aren’t the offspring from the same womb, but genetic similarities among human populations suggest equality among us.
AFAIK, the minor genetic differences predispose particular racial or ethnic groups to diseases.
It is well known that some diseases are more common in particular racial or ethnic groups than in others, for example, cystic fibrosis among people of European ancestry, sickle cell disease among those of African and Mediterranean ancestry, and Tay-Sachs disease among Ashkenazi Jews.
