Expanding the classical paradigm: what we have learnt from vertebrates about sex chromosome evolution
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 …

Sex chromosomes in meiotic, hemiclonal, clonal and polyploid hybrid vertebrates: along the 'extended speciation continuum'
We review knowledge about the roles of sex chromosomes in vertebrate hybridization and
speciation, exploring a gradient of divergences with increasing reproductive isolation …

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