The genome of <i>Litomosoides sigmodontis</i> illuminates the origins of Y chromosomes in filarial nematodes

2023-08-03

Abstract excerpt

Heteromorphic sex chromosomes are usually thought to have originated from a pair of autosomes that acquired a sex-determining locus and subsequently stopped recombining, leading to degeneration of the sex-limited chromosome. In contrast, in rhabditid nematodes, sex is determined by an X-chromosome counting mechanism and males are hemizygous for one or more X chromosomes (XX/X0). Some species of filarial nematodes,...
