Transitions in the heterogamety of sex chromosomes (eg, XY to ZW or vice versa)
fundamentally alter the genetic basis of sex determination, however the details of these …

The evolution of sex chromosomes can involve recombination suppression sometimes
involving structural changes, such as inversions, allowing subsequent rearrangements …

The development of non-recombining sex chromosomes has radical effects on the evolution
of discrete sexes and sexual dimorphism. Although dioecy is rare in plants, sex …

Most eukaryotes reproduce sexually and a wealth of different sex determination
mechanisms have evolved in this lineage. Dioecy or separate sexes are rare among …

Almost all species in the genus Salix (willow) are dioecious and willows have variable sex-
determining systems, the role of this variation in maintaining species barriers is relatively …

Background Salicaceae species have diverse sex determination systems and frequent sex
chromosome turnovers. However, compared with poplars, the diversity of sex determination …

Sex chromosomes can evolve when recombination is halted between a pair of
chromosomes, and this can lead to degeneration of the sex-limited chromosome. In the early …

Dioecy, the presence of separate sexes on distinct individuals, has evolved repeatedly in
multiple plant lineages. However, the specific mechanisms by which sex systems evolve and …

Dioecy has evolved numerous times in plants, but heteromorphic sex chromosomes are
apparently rare. Sex determination has been studied in multiple Salix and Populus …

Background Sex chromosomes have evolved independently multiple times in eukaryotes
and are therefore considered a prime example of convergent genome evolution. Sex …
