Genetic population structure of a long-finned squid photolologo edulis(Cephalopoda : Loliginidae)

商业捕捞的黄金酸squid Photololigo edulis的遗传种群结构是通过收集三个样本（294个个体）的两个季节性种群的样本进行实验，并将个人用于电波分析，经过测试的23个酶，10个酶被筛选用于聚合物。Clearly resolved enzyme phenotypes were obtained at seven （malate dehydrogenase，MDH-1型D1* 型D1，MDH-2型D1* 型D1，MDH-3型D1* 型D1，E.C. 1.1.1.37在7个位点上显示出遗传变异性的低水平的路由评分，与多态性位点的分布相比， P=0-0.1，平均每个位点的异质性=0.28-2.19 x10-D1.对七个多态位点的分布进行分析，提供了遗传分离的证据，以及遗传学类别的频率分布几乎适合的硬-温伯格期望。Nei的平均遗传距离在0.491-2.522（x10-D1-4-D1）之间的采样范围内，相应地，支持对squid遗传人口结构的看法是同源的。

Genetic population structure of the commercially fished loliginid squid Photololigo edulis was examined by collecting three samples (294 individuals) of two seasonal populations from the East China Sea, and subjecting individuals to electrophoretic analysis.Twenty-three enzymes were tested, and 10 enzymes were screened for polymorphism. Clearly resolved enzyme phenotypes were obtained at seven (malate dehydrogenase, MDH-1ィイD1*ィエD1, MDH-2ィイD1*ィエD1, MDH-3ィイD1*ィエD1, E.C. 1.1.1.37 ; phosphogluconate dehydrogenase, PGDHィイD1*ィエD1, E.C.1.1.1.44 ; aspartate aminotransferase, AAT-2ィイD1*ィエD1, E.C.2.6.1.1; adenylate kinase, AK-2ィイD1*ィエD1, E.C.2.7.4.3 ; phosphoglucomutase, PGMィイD1*ィエD1, E.C.5.4.2.2). Routine scoring at the 7 loci revealed low levels of genetic variability, with the proportion of polymorphic loci, P=0-0.1, mean heterozygosities per locus=0.28-2.19 x10ィイD1-2ィエD1.Analyses of allele frequencies at seven polymorphic loci provided no evidence of genetic separation, and the frequency distribution of genotypic classes almost fitted Hardy-Weinberg expectations for randomly mating population. Nei's mean genetic distances between samples ranged from 0.491-2.522(x10ィイD1-4ィエD1), respectively, supporting the opinion that genetic population structure of the squid is homogeneous.
