采用8对微卫星引物对合浦珠母贝12个家系的遗传多样与性状的相关性进行分析,结果显示,平均等位基因数(Ao)、平均有效等位基因数(Ae)、平均观测杂合度(Ho)、平均期望杂合度(He)和平均多态信息含量(PIC)等遗传参数与性状的表型参数总体上呈凸形曲线关系,表明中等遗传参数的家系性状表型普遍较好。但总体上,生长较快的家系,各遗传参数平均较大。 Eight pairs of microsatellite primers were used to analyze the genetic diversity and traits in 12 families of Pinctada copepods. The results showed that the average number of alleles (Ao), average effective alleles (Ae), average observed heterozygotes The phenotypic parameters of genetic parameters such as fitness (He), average expected heterozygosity (He) and mean polymorphism information content (PIC) were in a convex curve with the phenotypes of the traits, indicating that the phenotypic trait of pedigrees with moderate genetic parameters was generally good . However, on the whole, the faster growing families have larger average genetic parameters.
