西施舌3个自然群体杂合性的研究
Heterozygosity in 3 natural stocks of Coelmomactra antiquata (Spengler)
摘要
Abstract
Heterozygosity was investigated using an assay of vertical slab polyacrylamide gel electrophoresis in three Coelmomactra antiquate stocks from three sites: Beihai (Guangxi Province), Zhanggang (Fujian Province), Qidong (Jiangsu Province). 7 aliozymes were detected, and got 12 allozyme loci, 25 alleles, 4 loci (Sod-1, Mdh-1,Est-1, Est-3) with 1-7 alleles which are polymorphic. The results showed that the genetypic distribution observed at Sod-1, Est-1 in Zhanggang stock and Sod-1 in Beihai stock were corresponded with the Hardy-Wemberg equilibrium (P>0.05). But other loci in the three stocks were significant deviations from Hardy-Weinberg equilibrium (P<0.01). There was heterozygote deficiency existed in Est-1 in Qidong and Zhanggang stock (F>0), and heterozygote excess existed in other loci in the three stocks (F<0). The observed heterozygosity and expected heterozygosity per polymorphic locus per stock indicated that the germplasm resources of three C antiquate stocks were good.关键词
