Definitions related to pseudoautosomal regions:
-
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.NCI ThesaurusU.S. National Cancer Institute, 2021
-
Homologous chromosomal regions at either end of the X CHROMOSOME or Y CHROMOSOME. These two regions pair regularly at male MEIOSIS and undergo RECOMBINATION. Pseudoautosomal region 1 (PAR1) is located at the tip of the short 'p' arms (Xp22 and Yp11) and Pseudoautosomal region 2 (PAR2) is located at the tip of the long 'q' arms (Xq28 and Yq12).NLM Medical Subject HeadingsU.S. National Library of Medicine, 2021
