title: Isozymes in androgenetic and gynogenetic white amur, gynogenetic carp, and carp-amur hybrids.
abstract: Gynogentic and androgenetic progeny appeared in crosses between white amur, Ctenopharyngodon idella, and carp, Cyprinus carpio. Hemoglobin, plasma general proteins, and plasma isoenzymes were studied by electrophoresis to determine inheritance patterns. Electrophoretic bands indicated that gynogenetic white amur had no paternal inheritance from carp and that adrogenetic white amur also were pure white amur. Gynogeneiss in carp was confirmed by the absence of paternal inheritance. Hemoglobins, general proteins, and esterases distinguished the two species. Within a species there were no differences in proteins between gynogenetic, adrogenetic and normal fish. Lactate dehydrogenase (LDH) differed between carp and white amur and was a good marker for detecting heterologous inheritance in adrogenesis or gynogenesis because expression of LDH alleles from white amur was inhibited by the carp genome. Alkaline phosphatase and malate dehydrogenase had similar electrophoretic mobility in the two species.
