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 …

A 180 Myr-old female-specific genome region in sturgeon reveals the oldest known vertebrate sex determining system with undifferentiated sex chromosomes
Several hypotheses explain the prevalence of undifferentiated sex chromosomes in
poikilothermic vertebrates. Turnovers change the master sex determination gene, the sex …

The polyploid origins of crop genomes and their implications: A case study in legumes
Gene duplication and polyploidy are some of the most important, yet underappreciated,
evolutionary forces that have shaped all flowering plants on earth, and the crop plants that …

A frog with three sex chromosomes that co-mingle together in nature: Xenopus tropicalis has a degenerate W and a Y that evolved from a Z chromosome
In many species, sexual differentiation is a vital prelude to reproduction, and disruption of
this process can have severe fitness effects, including sterility. It is thus interesting that …

Functional dissection and assembly of a small, newly evolved, W chromosome-specific genomic region of the African clawed frog Xenopus laevis
Genetic triggers for sex determination are frequently co-inherited with other linked genes
that may also influence one or more sex-specific phenotypes. To better understand how sex …

Population genomics and subgenome evolution of the allotetraploid frog Xenopus laevis in southern Africa
Allotetraploid genomes have two distinct genomic components called subgenomes that are
derived from separate diploid ancestral species. Many genomic characteristics such as gene …
