Bird sex chromosomes play a unique role in sex-determination, and affect the sexual
morphology and behavior of bird species. Core waterbirds, a major clade of birds, share the …

How the avian sex chromosomes first evolved from autosomes remains elusive as 100
million years (My) of divergence and degeneration obscure their evolutionary history. The …

The study of sex determination and sex chromosome organization in nonmodel species has
long been technically challenging, but new sequencing methodologies now enable precise …

Sex chromosomes in birds have long been considered to be extremely stable. However, this
notion has lately been challenged by findings of independent autosome–sex chromosome …

Background Understanding sex-biased natural selection can be enhanced by access to well-
annotated chromosomes including ones inherited in sex-specific fashion. The eastern …

Sex chromosomes have evolved from the same autosomes multiple times across
vertebrates, suggesting that selection for recombination suppression has acted repeatedly …

Chromosomal organization is relatively stable among avian species, especially with regards
to sex chromosomes. Members of the large Sylvioidea clade however have a pair of neo-sex …

A high‐quality reference genome can be a valuable resource for threatened species by
providing a foundation to assess their evolutionary potential to adapt to future pressures …

Many organisms have separate sexes, ie, males and females. The presence of separate
sexes causes sex-specific selection regimes and sexual antagonism, which can lead to sex …

Sex chromosomes have evolved from the same autosomes multiple times across
vertebrates, suggesting that certain genomic regions are predisposed towards sex-linkage …
