Pseudoautosomal region

Definition(s)

The human Y chromosome is composed of two different parts: a pseudoautosomal region that is homologous to a region of the X chromosome and which is responsible for sex chromosome pairing and a Y-specific part that encodes the sex determining gene. Genes within the pseudoautosomal region are not sex linked.: Definition from: NCI Thesaurus via Unified Medical Language System at the National Library of Medicine
