“…Older larvae did not show the relationship. King (1985) found little evidence of a correlation between heterozygosity and growth rate in the herring, Clupea harengus, although there was a positive correlation between multi-locus heterozygosity and length. Beacham and Withier (1985) could not detect a difference in growth rate between homozygous and heterozygous pink salmon, Oncorhynchus gorbuscha.…”

Samples of young plaice were examined to see if there was any relationship between growth rate and individual heterozygosity, screened across five polymorphic enzyme loci (Pgm-1, Ada, Mdh-2, Pgi-2, aGpdh-1). Two out of 46 samples showed a significant negative correlation between growth rate and multi-locus heterozygosity; none showed a significant positive correlation. There was no overall tendency to negative or positive correlations. The largest sample (N = 689) showed no relationship between multi-locus heterozygosity and growth rate, although one of the five loci, aGpdh-1, showed a significant positive correlation. The only significant correlation in the next largest sample (N = 248) was between multi-locus heterozygosity and growth rate, and that was negative. Fish of intermediate growth rate were not significantly different in heterozygosity from faster or slower growing fish. There was no relationship between variability in growth rate and multi-locus heterozygosity. These findings are discussed in the context of similar surveys from other species, and the conclusion drawn that the universality of a positive relationship between growth rate and multi-locus heterozygosity remains to be established.

“…Enzyme heterozygosity is associated with both growth and developmental homeostasis in the herring, Clupea harengus (King, 1985). Mean length of fish increased with heterozygosity at five loci, and the asymptotic length of heterozygotes (324 ram) exceeded that of homozygotes (308 mm).…”

Developmental homeostasis, measured as either fluctuating asymmetry or variance of morphological characters, increases with enzyme heterozygosity in many, but not all, natural populations. These results have been reported for Drosophila, monarch butterflies, honeybees, blue mussels, side-blotched lizards, killifish, salmonid fishes, guppies, Sonoran topminnows, herring, rufous-collared sparrows, house sparrows, brown hares, white-tailed deer, and humans. Because heterozygosity at a few loci can not predict heterozygosity of the entiry genome, these loci must be detecting localized zones that influence the developmental environment.Studies of malate dehydrogenase in honeybees, Apis mellifera, and lactate dehydrogenase in killifish, Fundulus heteroclitus, revealed that developmental homeostasis varied with heterozygosity of individual loci. Heterozygotes differed from homozygotes in fluctuating asymmetry, morphological variance, and in correlations between morphological characters.The protein loci in these studies code for enzymes, and therefore do not directly influence morphological characters. However, some enzymatic loci substantially influence metabolism, and contribute to variation in the amount of energy available for development and growth. This argument can be made most convincingly for the LDH polymorphism in killifish. LDH genotypes differ in enzyme kinetic properties that measure differences in physiological efficiency, and these differences produce measurable and predictable differences in physiology and development. Under environmental conditions which impose a stress upon development, genotypes at these loci may have different amounts of energy available for development, and consequently exhibit different levels of developmental homeostasis.
