Analysis of genetic structure of Jamunapari goats by microsatellite markers

Genetic variation at 23 microsatellite loci, population structure, and genetic bottleneck hypothesis were examined for Jamunapari goat population found in Etawah, Uttar Pradesh, India. Estimates of genetic variability such as effective number of alleles and gene diversities revealed substantial genetic variation frequently displayed by microsatellite markers. Number of alleles observed across the microsatellite loci varied from 2 to 10 with an overall mean of 4.913 ± 1.905. Average polymorphism across the studied loci and expected gene diversity in the population were 1.066 ± 0.510 and 0.528 ± 0.237, respectively. Population was observed to be significantly differentiated into different groups, and showed fairly high level of inbreeding (f = 0.189 ± 0.049) and global heterozygote deficit. Bottleneck analysis indicated the introduction of unique/rare alleles by immigrants.
