Aquaculture is one of the most efficient modes of animal protein production and plays an
important role in global food security. Aquaculture animals exhibit extraordinarily diverse …

Genomic analysis of many nonmodel species has uncovered an incredible diversity of sex
chromosome systems, making it possible to empirically test the rich body of evolutionary …

Contrary to classic theory prediction, sex-chromosome homomorphy is prevalent in the
animal kingdom but it is unclear how ancient homomorphic sex chromosomes avoid …

Although sex is a fundamental component of eukaryotic reproduction, the genetic systems
that control sex determination are highly variable. In many organisms the presence of sex …

Animal sex chromosomes typically carry the upstream sex-determining gene that triggers
testis or ovary development and, in some species, are regulated by global dosage …

The genetic architecture of speciation, ie, how intrinsic genomic incompatibilities promote
reproductive isolation (RI) between diverging lineages, is one of the best-kept secrets of …

Sex differences in overall recombination rates are well known, but little theoretical or
empirical attention has been given to how and why sexes differ in their recombination …

Prevailing models of sex-chromosome evolution were largely inspired by the stable and
highly differentiated XY pairs of model organisms, such as those of mammals and flies …

The loss of recombination between sex chromosomes has occurred repeatedly throughout
nature, with important implications for their subsequent evolution. Explanations for this …

Until recently, the field of sex chromosome evolution has been dominated by the canonical
unidirectional scenario, first developed by Muller in 1918. This model postulates that sex …
