Populations of several marine bivalves exhibit significant deficiencies of heterozygotes (compared with the Hardy-Weinberg expectations) at some allozyme loci (Berger, 1983; Singh and Green, 1984; Zouros and Foltz, 1984). These deficiencies have usually been explained by invoking nonrandom mating, selection, or population structure (Wahlund effect). Less attention has been paid to the possibility that the deficiencies are due to the occurrence of null (nonreactive) alleles or to other factors… CONTINUE READING
