Do silverback gorillas mate with all the females?

Mating in Gorillas

Do gorillas mate with their offspring?

Female gorillas usually don’t mate with their closest relatives, their father and brothers. In the wild, when they’ve reached the right age, they leave their group, and choose a new group with a silverback who appeals to them.
