title: The localization of genes for HPRT, G6PD, and alpha-GAL onto the X-chromosome of domestic pig (Sus scrofa domesticus).
abstract: Pig--mouse somatic cell hybrids were obtained from fusion of HPRT--mouse cells (RAG) and pig lymphocytes. The pig-mouse hybrids examined apparently retained on the average only 9 to 15 pig chromosomes. Seven of the hybrid clones were karyotyped to determine the pig chromosome constitution, and the same hybrid clones were tested electrophoretically for the expression of pig hypoxanthine-guanine phosphoribosyltransferase (HPRT), glucose-6-phosphate dehydrogenase (G6PD), and alpha-galactosidase (alpha-GAL) phenotypes. All five of the hybrid clones which had retained the pig X-chromosome exhibited concordant expression of pig HPRT, G6PD, and alpha-GAL enzymes. These data indicate that the genes HPRT, G6PD, and alpha-GAL are located on the X-chromosome of the domestic pig.
