Quantitative analyses of genotypic relationships between parents and their diploid and triploid offspring sib populations, induced by inhibiting release of first or second polar body, have made it possible to estimate rate ofgene-centromere recombination at phosphogluconate dehydrogenase and phosphoglucomutase loci and to disclose differential contribution of oocytes to triploid offspring, in relation to the latter locus in the Pacific abalone Haliotis discus hannai.
In the present work, application ofthe similar analyses on parentage of genotypic compositions allowed to estimate rate of gene-centromere recombination and fitness or differential contribution of oocytes to triploid offspring at each of the loci coding electrophoretic and thermostability variations of phosphoglucose isomerase and esterase and to discuss probable integrated effect of genotypes at multiple loci of parental female animals on their relative contribution in production of triploid offsprings.
