Description

ABSTRACT Genetic structure of four cultured Haliotis diversicolor supertexta populations were investigated using the assay of vertical slab polyacrylamide gel electrophoresis. Low levels of genetic diversity of populations was found: mean numbers of alleles per locus ranged from 1.4 to 1.5: proportions of polymorphic loci ([P.sub.o.99%]) ranged from 27.78 to 33.33; observed heterozygosities ranged from 0.120 to 0.150; expected heterozygosities ranged from 0.123 to 0.131. The results showed that the coefficient of gene differentiation among populations was low ([F.sub.ST] = 0.04), gene flow among populations was large (Nm = 6). Genetic structure was very similar among four cultured populations. The genetic distances between any two of the four populations were 0.002-0.009, with an average of 0.0047. KEY WORDS: Haliotis diversicolor supertexta, allozyme, genetic structure, genetic diversity, genetic differentiation
