Sex -chromosome research in plants is fragmented among many in most land plant lineages excepting gymnosperms (Renner, ). Both X and Y probably evolved from a pair of ordinary chromosomes that have nothing to do with sex (also known as autosomes). The story.

Sex differences in fitness and selection for centric fusions between sex-chromosomes and autosomes. Citation Paper's citation count computed by Scopus. Turnover of sex chromosomes can also be triggered by the degeneration of the Y and W chromosome, which commonly follows the cessation of recombination [66] , [67] , and will result in the replacement of a low-fitness Y or W chromosome with a nondegenerate one [68]. Valenzuela N, Neuwald JL, Literman R Transcriptional evolution underlying vertebrate sexual development. Suppression of recombination between the sex chromosomes, associated with degeneration of the non-recombining region of the Y chromosome, results in the morphological and genetic differentiation of sex chromosomes.

Huber , and R. Moreover, old gene-poor Y chromosomes that are tens of millions of years old, such as the Drosophila Y [] , actually show a net rate of gene gain rather than gene loss []. All three involve a master-switch sex-determining gene, which led to the birth of Myth 2.
