Estimating rate of gene-centromere recombination at some isozyme loci in Haliotis diversicolor diversicolor and H. discus hannai

Abstract

Analyses on the genotypic compositions in parents and their offspring populations induced by genome manipulation have made it possible to estimate rates of gene-centromere recombination at the four loci in Haliotis diversicolor diversicolor and at the ten loci in H. discus hannai. The present paper presents the results of the similar analyses on genotypic parentages to estimate the rates at the additional four loci in H. diversicolor diversicolor and that at additional one locus in H. discus hannai. Comparisons of the rate at each of seven homologous loci between the two species indicated that the estimates were close each other at the four loci coding phosphoglucomutase, leucine-aminopeptidase, malic enzyme, and superoxide dismutase and that those in H. discus hannai revealed approximately two times greater than those in H. diversicolor diversicolor at the three loci coding phosphoglucose dehydrogenase, phosphoglucose isomerase and mannosephosphate isomerase.
