The past two decades have seen extensive growth of sexual selection research. Theoretical
and empirical work has clarified many components of pre-and postcopulatory sexual …

Recent years have seen a rapid expansion in the scope of quantitative genetic analyses
undertaken in wild populations. We illustrate here the potential for such studies to address …

Sexual reproduction is a fundamental aspect of life. It is defined by the occurrence of meiosis
and the fusion of two gametes of different sexes or mating types. Sex-determination …

Reptiles use pterin and carotenoid pigments to produce yellow, orange, and red colors.
These conspicuous colors serve a diversity of signaling functions, but their molecular basis …

Mathematical models have played an important role in the development of sexual selection
theory. These models come in different flavors and they differ in their assumptions, often in a …

The profound differences in gene expression between the sexes are increasingly used to
study the molecular basis of sexual dimorphism, sexual selection and sexual conflict …

Many studies have been aimed at understanding the maintenance of female infidelity in
socially monogamous birds. Because engaging in extrapair copulations (EPCs) is believed …

The rate of evolution of population mean fitness informs how selection acting in
contemporary populations can counteract environmental change and genetic degradation …

Interbreeding between species (hybridization) typically produces unfit offspring. Reduced
hybridization should therefore be favored by natural selection. However, this is difficult to …

A fundamental question for both evolutionary biologists and breeders is the extent to which
genetic correlations limit the ability of populations to respond to selection. Here I view this …
