title: Erythrocyte galactose-1-phosphate uridyltransferase and galactokinase levels in twins.
abstract: The levels of the two enzymes, GAL-1-PUT and GAL-KIN, have been examined in a sample of 35 MZ and 45 DZ twin pairs of both sexes. The activities of these enzymes do not appear to be influenced by sex. The role of genetic factors appears to be rather limited in the case of GAL-1-PUT, but much higher in the case of GAL-KIN.
