Amongst Temminck's red colobus living in the Abuko Nature Reserve, The Gambia, the mechanism for avoiding close inbreeding may depend on the form of inbreeding. Mother-son inbreeding may be avoided through learned behaviour and possibly secondary transfer by the mother. Father-daughter inbreeding may be limited due to transfer and demographic patterns but also aggression directed at the male from the mountee's mother. Maternal brother-sister inbreeding may be avoided through female transfer patterns. Presummed paternal brothersister inbreeding is infrequent but does occur and is not discouraged or avoided.
