Many separate-sexed organisms have sex chromosomes controlling sex determination. Sex
chromosomes often have reduced recombination, specialized (frequently sex-specific) gene …

Although the molecular mechanisms underlying many developmental events are conserved
across vertebrate taxa, the lability at the top of the sex‐determining (SD) cascade has been …

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 …

Heterogametic sex chromosomes have evolved independently in various lineages of
vertebrates. Such sex chromosome pairs often contain nonrecombining regions, with one of …

Sex-determination genes are among the most fluid features of the genome in many groups
of animals,. In some taxa the master sex-determining gene moves frequently between …

Cichlid fishes constitute one of the most species-rich families of vertebrates. In addition to
complex social behaviour and morphological versatility, they are characterised by extensive …

It is commonly assumed that sex chromosomes evolve recombination suppression because
selection favours linkage between sex-determining and sexually antagonistic genes …

I review theoretical models for the evolution of supergenes in the cases of B atesian mimicry
in butterflies, distylous plants and sex chromosomes. For each of these systems, I outline the …

Several models have been proposed to suggest how the evolution of sex-determining
mechanisms might contribute to speciation. Here, we describe the inheritance of sex in 19 …

Many animal taxa show frequent and rapid transitions between male heterogamety (XY) and
female heterogamety (ZW). We develop a model showing how these transitions can be …
