Analysis of Genetic Structure and Diversity of Chai Chicken Breed Using Microsatellite Markers

摘要

Genetic diversity of 10 microsatellite locis were analyzed in Chai chicken breeds. Allele frequency, effective number of alleles, heterozygosity, Polymorphism Information Content (PIC), F-statistics, migration rate were calculated. The results showed that the average observed Heterozygosity (Ho) and PIC amongst populations ranged from 0.5353-0.5614 and 0.5108-0.5199, respectively. The genetic diversity was very rich and was of high selective potency. To analyze population structure, pairwise Fst coefficients explained only 8.4% variability from the breed differences, the remaining variability stems from individual differences. Gene flow of microsatellite loci was 2.7794 indicate no significant genetic differentiation among populations.
