A diverse array of sex determination (SD) mechanisms, encompassing environmental to
genetic, have been found to exist among vertebrates, covering a spectrum from fixed SD …

The discovery of the Sry gene in 1990 triggered a revolution in our understanding of sex
determination. More recently, advances in non-model organisms have been fuelled by the …

Sex chromosomes have evolved many times in animals and studying these replicate
evolutionary “experiments” can help broaden our understanding of the general forces …

Differentiated sex chromosomes in mammals and other vertebrates evolved independently
but in strikingly similar ways. Vertebrates with differentiated sex chromosomes share the …

Are homologies in vertebrate sex determination due to shared ancestry or to limited options?

Sex chromosomes are a great example of a convergent evolution at the genomic level,
having evolved dozens of times just within amniotes. An intriguing question is whether this …

The ability to identify genetic markers in nonmodel systems has allowed geneticists to
construct linkage maps for a diversity of species, and the sex-determining locus is often …

Reptiles epitomize the variability of reproductive and sex determining modes and
mechanisms among amniotes. These modes include gonochorism (separate sexes) and …

Important technological advances in genomics are driving a new understanding of the
evolution of sex determination in vertebrates. In particular, comparative chromosome …

To explain the frequency and distribution of heteromorphic sex chromosomes in the lizard
genus Anolis, we compared the relative roles of sex chromosome conservation versus …
