Analyses of genetic relationships between parents and their diploid and triploid offsprings have made it possible to estimate rate of gene-centromere recombination at phosphogluconate dehydrogenase locus in the pacific abalone, Haliotis discus hannai. Differential survivals by genotype of thermostability variations of enzymes of animals against thermal stresses have been reported on some species under natural or experimental conditions of environments. The present work analyses parentage of genotype compositions at phosphoglucomutase (Pgm) thermostability locus in the normal diploid and triploid sib populations induced by genome mani-pulation, estimates rate of gene-centromere recombination at the locus, and discusses probable association between differential contribution of ootids/meiotic drive and their genotypes at Pgm thermostability locus in the pacific abalone, Haliotis discus hannai.
