Mate preferences may operate in part to mitigate the threats posed by infectious disease. In
this paper, we outline various ways in which preferring healthy mates can offer direct …

Background Due to its high polymorphism and importance for disease resistance, the major
histocompatibility complex (MHC) has been an important focus of many vertebrate genome …

Hamilton and Zuk proposed that females choose mates based on ornaments whose
expression is dependent on their genetically based resistance to parasites. The major …

Here we show that sexual selection can have an effect on the rate of mutation. We simulated
the fate of a genetic modifier of the mutation rate in a sexual population with and without …

Charles Darwin published his second book “Sexual selection and the descent of man” in
1871 150 years ago, to try to explain, amongst other things, the evolution of the peacock's …

The major histocompatibility complex (MHC) has been known to play a critical role in
immune recognition since the 1950s. It was a surprise, then, in the 1970s when WKH fiUVW …

The major histocompatibility complex (MHC) is characterized by a birth and death model of
evolution involving gene duplication, diversification, loss of function, and deletion. As a …

Background Females can potentially assess the quality of potential mates using their
secondary sexual traits, and obtain" good genes" that increase offspring fitness. Another …

The major histocompatibility complex (MHC) plays a key role in pathogen recognition as a
part of the vertebrate adaptive immune system. The great diversity of MHC genes in natural …

Biologists have known for decades that many traits involved in competition for mates or other
resources and that influence mate choice are exaggerated, and their expression is …
