AB  - With growing concern about maintenance of genetic variation 
  and conservation of gene resources, the question arises on how to preserve the 
  gene pool of a species. In this study, genetic diversity of 10 microsatellite 
  locis was analyzed in Chai chicken breed. Allele frequency, effective number 
  of alleles, heterozygosity, Polymorphism Information Content (PIC), F-statistics, 
  migration rate and genetic bottleneck hypothesis were calculated. Number of 
  alleles observed across the microsatellite loci varied from 3-8 with an overall 
  mean of 5.0. Average observed Heterozygosity (Ho) and PIC amongst populations 
  ranged from 0.5353-0.5614 and 0.5108-0.5199, respectively. To analyze population 
  structure, pair wise Fst coefficients explained only 8.4% variability from the 
  breed differences, the rest variability stems from individual differences. Gene 
  flow of microsatellite loci was 2.7794, the result showed no significant genetic 
  differentiation among populations. Bottleneck analysis indicated heterozygosis 
  was obvious and group did not in the balance between mutation and excursion 
  for its bottleneck. Researchers suggest that the moderate level of genetic diversity 
  retained in Chai populations has the potential to supply sufficient genetic 
  diversity for the species conservation through the recruitment of Chai resources 
  in origin region and individuals exchanging among conservation farms.
