Exchange of genetic information between therian X and Y chromosome gametologs in old evolutionary strata

12 Sept 2017

Abstract excerpt

Abstract Therian X and Y sex chromosomes arose from a pair of autosomes. Y chromosomes consist of a pseudoautosomal region that crosses over with the X chromosome and a male‐specific Y‐chromosomal region that does not. The X chromosome can be structured into “evolutionary strata”. Divergence of X‐chromosomal genes from their gametologs is similar within a stratum, but differs among strata, likely caused by a...
