How consistent are the evolutionary trajectories of sex chromosomes shortly after they form?
Insights into the evolution of recombination, differentiation, and degeneration can be …

Sex chromosomes turn over rapidly in some taxonomic groups, where closely related
species have different sex chromosomes. Although there are many examples of sex …

Recombination suppression leads to the structural and functional differentiation of sex
chromosomes and is thus a crucial step in the process of sex chromosome evolution …

Closely related species of fishes often have different sex chromosome systems. Such rapid
turnover of sex chromosomes can occur by several mechanisms, including fusions between …

Recent discoveries of sex chromosome diversity across the tree of life have challenged the
canonical model of conserved sex chromosome evolution and evoked new theories on …

Recombination often differs markedly between males and females. Here we present the first
analysis of sex-specific recombination in Gasterosteus sticklebacks. Using whole-genome …

Sexual antagonism, or conflict between the sexes, has been proposed as a driving force in
both sex-chromosome turnover and speciation. Although closely related species often have …

Diverse sex-chromosome systems are found in vertebrates, particularly in teleost fishes,
where different systems can be found in closely related species. Several mechanisms have …

Intralocus sexually antagonistic selection occurs when an allele is beneficial to one sex but
detrimental to the other. This form of selection is thought to be key to the evolution of sex …

Background Studies of closely related species with different sex chromosome systems can
provide insights into the processes of sex chromosome differentiation and evolution. To …
