MHC class II beta sequence diversity in the deer mouse (Peromyscus maniculatus): implications for models of balancing selection.

abstract：:Red carotenoid colours in birds are widely assumed to be sexually selected quality indicators, but this rests on a very incomplete understanding of genetic mechanisms and honesty-mediating costs. Recent progress was made by the implication of the gene CYP2J19 as an avian carotenoid ketolase, catalysing the synthesis o...
