| 摘 要： | 采用水平凝胶电泳技术对红鳍东方鲀养殖群体进行了同工酶分析。本实验采用肌肉和肝脏两种组织,分析了8种酶,检测到9个位点,在0.99水平上,PGM*和IDHP*表现为多态,MPI*、LDH*、AAT*、SOD*、MDH-1*、MDH-2*和G3PDH*均为单态,多态位点比例为0.2222,平均预期杂合度为0.0998,实际观测杂合度为0.0467,平均有效等位基因数目为1.1840,PGM*位点的遗传偏离指数为-0.0707,杂合子缺失,IDHP*位点无杂合子,遗传偏离指数为-1。

| Abstract: | Isozyme analysis was conducted on cultured Takifugu rubripes population by using horizontal starch gel electrophoresis. Nine loci were examined from eight enzymes, and PGMand IDHP were polymorphic when the most common allele was less than or equal to 0.99. The proportion of polymorphic was 0.222 2, the average observed heterozygosity was 0.046 7, and the expected heterozygosity was 0.099 8. The average effective number of alleles was 1.184 0. |
