MHC-Based Mate Choice in Wild Golden Snub-Nosed Monkeys.

The genes of the major histocompatibility complex (MHC) are an important component of the vertebrate immune system and play a significant role in mate choice in many species. However, it remains unclear whether female mate choice in non-human primates is based on specific functional genes and/or genome-wide genes. The golden snub-nosed monkey () lives in a multilevel society, which consists of several polygynous one-male-several-female units.
