| 摘 要： | 茶花鸡是我国具有独特遗传特性的地方家禽品种,为了进一步阐明其群体遗传变异和遗传结构状况,采用了33个家鸡特异性的微卫星标记对该鸡种自然群体中30个个体进行了多态性电泳检测。33个微卫星座位共检测到105个等位基因,所有座位都呈现出多态性,每个座位的等位基因数在2~5个之间,平均每个座位等位基因数3.20个。群体平均杂合度和平均多态信息含量分别为0.612 9和0.527 6。结果表明,茶花鸡自然群体遗传多样性较丰富。

| Abstract: | Chahua chicken is a unique Chicken Breed in China.In order to assess its genetic variability and population structure further,33 chicken-specific microsatellite loci were analyzed for a total of 30 individuals from small remote villages by using polyacrylaminde gel electrophoresis.A total of 105 alleles were detected across the 33 loci assayed.All the loci were polymorphic and the number of alleles varied from two to five,giving a mean number of 3.20 alleles per locus.The average heterozygosity and polymorphism information content of 33 microsatellite loci were 0.612?9 and 0.527?6,respectively.The results indicate that Chahua Chicken breed has high genetic diversity. |
