Allozymic variation in a North American colony of cepaea nemoralis

Abstract

Starch gel electrophoresis of foot-muscle extracts from over 400 individuals of the land snail Cepaea nemoralis collected from 10 different populations in the Lexington, Virginia, colony revealed nine scorable loci. Two of these, LAP II and PGM II, proved to be polymorphic with two and three alleles, respectively. Each of the populations surveyed was in Hardy-Weinberg equilibrium at both loci, and laboratory crosses have confirmed the basis of the polymorphism. © 1974 The Genetical Society of Great Britain.
