摘要
采用水平凝胶电泳技术对星突江鲽(Platichthys stellatus)养殖群体进行了同工酶分析。筛选了9种酶,检测到15个位点,在0.99水平上,仅PGM*位点表现为多态,LDH*、SDH*、G3PDH*、GPI-1*、GPI-2*、GPI-3*、IDHP*、SOD-1*、SOD-2*、SOD-3*、MDH-1*、MDH-2*、MPI-1*和MPI-2*均为单态,多态位点比例为6.67%,实际观测杂合度为0.0098,预期杂合度为0.0303,平均有效等位基因数目为1.0557。结果表明,星突江鲽养殖群体的遗传多样性水平较低。
Horizontal starch gel electrophoresis was used to investigate the genetic diversity of a cultured Platichthys stellatus stock.Only PGM^＊ locus was polymorphic among fifteen loci which were examined from nine enzymes while the most common allele was less than or equal to 0.99.The proportion of polymorphic loci was 6.67%,the mean observed heterozygosity was 0.0089,and the mean expected heterozygosity was 0.0303.The average effective number of alleles was 1.0557.
