Despite the prevalence of sexual reproduction across eukaryotes, there is a remarkable
diversity of sex‐determination mechanisms. The underlying causes of this diversity remain …

The vast majority of eukaryotic organisms reproduce sexually, yet the nature of the sexual
system and the mechanism of sex determination often vary remarkably, even among closely …

We compiled information from the literature on the taxonomic distributions in extant teleost
fishes of alternative sex-determination systems: male-heterogametic (XY) gonochorism …

Sex determination, due to the obvious association with reproduction and Darwinian fitness,
has been traditionally assumed to be a relatively conserved trait. However, research on …

Sex determination is typically classified as either genotypic or environmental. However, this
dichotomy obscures the developmental origin and evolutionary modification of determinants …

The molecular mechanisms that control sexual dimorphism are very different in distantly
related animals. Did sex determination arise several times with different regulatory …

Sex chromosomes vary greatly in their age and levels of differentiation across the tree of life.
This variation is largely due to the rates of sex chromosome turnover in different lineages; …

A surprising diversity of mechanisms controls sex determination of vertebrate organisms,
even among closely related species. Both genetic and temperature-dependent systems of …

Sex allocation theory is often able to make clear predictions about when individuals should
facultatively adjust their offspring sex ratio (proportion male) in response to local conditions …

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 …
