Abstract
Twenty-eight American mink × Chinese hamster somatic cell hybrids were analysed for the expression of mink enzymes and the segregation of mink chromosomes. The results demonstrated that the gene for enolase-1 is located on the long arm of mink chromosome 2, and those for hexokinase-1 and adenosine kinase, on its short arm. Segregation analysis of mink chromosomes and mink acid phosphatase-2, mannose phosphate isomerase, inosine triphosphatase and aconitase-1 provided data allowing us to assign the genes for these markers to mink chromosomes 7, 10, 11 and 12, respectively. The expression of mink α-galactosidase was highly coincidental with mink × chromosome as well as with its markers: hypoxanthine-phosphoribosyltransferase, glucose-6-phosphate dehydrogenase and phosphoglycerate kinase-1. This result confirms the assignment of the gene for α-galactosidase to the mink × chromosome.
