In light of our discussion of adaptive variation and MHC last week, I thought this might be an interesting article:
http://rspb.royalsocietypublishing.org/content/275/1634/555.full.pdf+html?sid=e5ace2c2-e9e3-4029-b9b3-ab75a6b17dd8
Based on study of the promiscuous grey mouse lemur in a wild population, the authors conclude that while no pre-copulatory MHC driven mate choice was evident, it was clear that there was post-copulatory mate choice in favor of MHC diversity between the mother and potential fathers. They further propose that some degree of cryptic female choice may be at play to promote immune diversity among offspring.
