Shell length and electrophoretic heterozygosity at six enzyme loci were scored in juveniles of 30 hatchery-grown families and in adults of 10 field-grown families of the blue mussel Mytilus edulis. A total of 4 809 offspring were scored. We found no consistent pattern in the correlations between she

β¦ Synopsis
There is a small but significant positive correlation between individual locus estimates of heterozygosity and subunit molecular weight in vertebrate dimeric enzymes. This correlation is smaller than that previously shown to exist for Drosophila dimers, and some possible reasons for this are explored. Data for vertebrate tetrameric enzymes are less extensive but appear to give similar trends to those shown by dimers. It is concluded that enzyme heterozygosity is influenced by both subunit size and quaternary structure.

Data from published sources were used to compare the numbers of different electrophoretic alleles of 29 monomeric and dimeric human enzymes to their respective subunit molecular weights. Only those human enzymes were considered for which the total sample sizes were in excess of 2000 individuals. Cor
Haploid male and diploid female honey bees, Apis mellifera, from colonies headed by queens polymorphic at the malate dehydrogenase (MDH) locus were examined for the influence of MDH genotype and heterozygosity on the size and asymmetry of six morphological characters. Although there were significant
