美国红鱼养殖种群的同工酶酶谱及其生化遗传初步分析

Preliminary analysis on isoenzyme diagram and bio-chemistry genetics of the cultivated population of red drum (Sciaenops ocellatus)

利用水平淀粉凝胶电泳技术 ,对 5 0尾美国红鱼肌肉及肝脏组织进行了 14种同工酶的初步分析。结果表明 ,美国红鱼多态位点比例 P=0 .2 92 ,实际平均杂合度 H o=0 .0 5 7,预期杂合度 H e=0 .10 8,每个位点的有效等位基因数 Ae=1.10 8,Hardy- Weinberg遗传偏离指数 D=- 0 .4 72。

Horizontal starch gel electrophoresis was used to analyze 14 isoenzymes of tissues of muscle and liver of red drum, Sciaenops ocellatus primarily. The results showed that the ratios of polymorphic loci were P =0 292, actual mean heterozygosity was H o=0 057, H e=0 108, the effective number of allele was A e=1 108. The genetic deviation index of hardy weinberg was D =0.472.
