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 …

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 canonical model of sex-chromosome evolution predicts that, as recombination is
suppressed along sex chromosomes, gametologs will progressively differentiate, eventually …

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 …

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

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 …

Several hypotheses explain the prevalence of undifferentiated sex chromosomes in
poikilothermic vertebrates. Turnovers change the master sex determination gene, the sex …

Subdivided Pleistocene glacial refugia, best known as “refugia within refugia”, provided
opportunities for diverging populations to evolve into incipient species and/or to hybridize …

Triggers and biological processes controlling male or female gonadal differentiation vary in
vertebrates, with sex determination (SD) governed by environmental factors or simple to …

A major reason for studying plant sex chromosomes is that they may often be
'young'systems. There is considerable evidence for the independent evolution of separate …
