Pseudoautosomal region


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.
