The genome of Litomosoides sigmodontis illuminates the origins of Y chromosomes in filarial nematodes
16 Jan 2024
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. The majority of nematode species lack heteromorphic sex chromosomes and determine sex using an X-chromosome counting mechanism, with males being hemizygous for one or more X chromosomes...
