Abstract
Starch gel electrophoresis was used to examine the generic separation of the sphaeriid clams Musculium and Sphaerium. Loci (25) from 13 enzyme systems were resolved. Major differences in electrophoretic patterns were observed, and these appear to support the generic separation of Musculium and Sphaerium. S. occidentale (Lewis), considered to be intermediate in form between Musculium and Sphaerium, is more closely related (electrophoretically) to other species of Sphaerium than to Musculium. The phenotypic convergence of S. occidentale with Musculium and its genotypic divergence from other Sphaerium spp. can be related to habitat characteristics of these forms.This publication has 3 references indexed in Scilit:
