The recent increase in available molecular and genomic data for diverse taxa helps to shed
new light on long-standing theories. Research into sex chromosome evolution has …

When females prefer mates with rare phenotypes, sexual selection can maintain rather than
deplete genetic variation. However, there is no consensus on why this widespread and …

The Y chromosome is theorized to facilitate evolution of sexual dimorphism by accumulating
sexually antagonistic loci, but empirical support is scarce. Due to the lack of recombination …

Color variation is one of the most obvious examples of variation in nature, but biologically
meaningful quantification and interpretation of variation in color and complex patterns are …

Sexual dimorphism typically arises as a result of sexual selection or sex-specific natural
selection. Species that exhibit cryptic coloration provide an excellent system for studying sex …

Genomic regions sometimes show patterns of genetic variation distinct from the genome-
wide population structure. Such deviations have often been interpreted to represent effects …

The extraordinary variation in male guppy coloration has proven a powerful model for
studying the interplay of natural and sexual selection. Many guppy populations exhibit …

Progressive recombination loss is a common feature of sex chromosomes. Yet, the
evolutionary drivers of this phenomenon remain a mystery. For decades, differences in trait …

The genetic basis of morphological variation provides a major topic in evolutionary
developmental biology. Fish of the genus Danio, containing the model species zebrafish …
