Genetic Diversity of Daweishan Mini Chickens Based on Microsatellite Markers
摘要
Abstract
Daweishan Mini chicken is unique chicken breed in China, which distributes in the tropic and sub-tropic zone in Pingbian county of Yunnan Province. 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 65 alleles were detected across the 33 loci assayed． The number of alleles varied from 1 to 3,giving a mean number of 1.9697 alleles per locus．The number of effective alleles ranged from 1.00 to 2.63 and the mean of number of effective alleles was 1.6846 for per locus. The average heterozygosity and polymorphism information content of 33 microsatellite loci were 0.1737 and 0.3279． The results indicate that Daweishan Mini chicken has low heterozygosity and polymorphism information content and high homozygosity. They are a containing primitive chicken breed without hybrid with other breed and showed high genetic consistency.关键词
