Estimating genetic distances in indigenous poultry germplasm using infinite allele model

Abstract

Microsatellite data from 26 loci was generated in four poultry populations using standard procedures. The data were subjected to analysis for the estimation of genetic distances among 4 populations/breeds of Indian poultry. viz. Miri.
Kashmir Favorolla, Aseel and Nicobari. The various genetic distances that were estimated under the Infinite allele model
were Nei's Standard. Nei's minimum, Nei's D A' Reynold's distance, Cavalli- Sforza and Edward's chord distance Stephen's proportion of shared alleles, Roger's distance and its modification by Wright, and Latter's F ST' The genetic distances were utilized for the preparation of the phylogenetic tree using UPGMA and neighbour joining algorithms. The trees obtained
were prepared using populations as unit and also by estimation of inter-individual distances using multilocus genotypes. The tree/topology obtained using Nei's D A was considered to be most appropriate because this could be backed by certain
statistical criterion as well as from historical and demographic perspective. Nicobari fowl WaS more closely related with
Aseel followed by Mid population/breed. The population of Kashmir Favorolla was a distinct entity.
