It’s more common for males to be dominant in Primates. A few reasons for this are:
Males are usually bigger and stronger than females.
Males are usually more aggressive and competitive.
Males are better at gaining support of the group.
Species who have a male dominant hierarchy are Chimpanzees and Capuchins.Male dominance
Female dominance isn’t as common as male dominance in Primates. Most times, females are able to dominate males by uniting as a group. One exception is the Ringtailed Lemur. Males are submissive without aggression from a group of females. In many instances where females dominate, they inherit their status at birth from their mother. In female dominated socieities, males usually leave the group around a certain age in order to prevent inbreeding.Female Dominance
