利用微卫星标记分析长顺绿壳蛋鸡的遗传多样性

利用8对微卫星引物对长顺绿壳蛋鸡遗传多样性进行检测。结果表明,该群体的平均有效等位基因数为3.585 6个,平均多态信息含量为0.659 7,平均期望杂合度为0.713 1,平均基因杂合度为0.710 2,表明长顺绿壳蛋鸡群体遗传变异较大,遗传多样性较为丰富。研究结果为长顺绿壳蛋鸡品种资源合理保护与开发利用提供了科学依据。

Analysis of Genetic Diversity of Changshun Blue-eggshell Chicken based on Microsatellite Marker

Eight pairs of microsatellite primers were used to detect genetic diversity of Changshun blue-eggshell chicken. The results show that the average effective number of alleles, average polymorphism information content, average expected heterozygosity, and average gene heterogeneity in the population were 3.585 6, 0.659 7, 0.713 1, and 0.710 2 respectively,indicating that the population of Changshun blue-eggshell chicken has great genetic variation and rich genetic diversity. The results can provide scientific references for rational protection, development and utilization of Changshun blue-eggshell chicken.
