chromosome 15, but an XY system has changed to a ZW system. We studied the detailed …

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

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

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

Sex chromosome turnover has occurred in many groups, and is mediated by the
translocation or duplication of apical sex-determining genes, or the replacement of original …

Dioecious Salix evolved more than 45 million years ago, but have homomorphic sex
chromosomes, suggesting that turnover event (s) prevented major differentiation. Sex …

Almost all species in the genus Salix (willow) are dioecious, but some have male and some
female heterogamety, and the chromosomal location of the sex-linked regions (termed …

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 …
