title: Analysis of 22 heterologous microsatellite markers for genetic variability in Indian goats.
abstract: The genetic variability of 22 heterologous microsatellite markers was analyzed in two Indian goat breeds, namely Bengal and Chegu. The heterozygosity, polymorphism information content (PIC), and probability of identity of two individuals were calculated for all microsatellite loci in both the breeds. The observed number of alleles varied between 4 and 13 at the studied microsatellite loci. The evaluated microsatellite loci exhibited high mean heterozygosity of 0.69 +/- 0.11 and 0.66 +/- 0.07 in Bengal and Chegu goats, respectively. The mean PIC values of the studied loci in these breeds were 0.79 +/- 0.08 and 0.78 +/- 0.05, respectively. The probability of identity of two random individuals from different breeds, taking into account, all the 22 microsatellite loci was as low as 5.523 x 10(-40). On the basis of these results, we propose that these microsatellite markers may be used with reliability for studying genetic diversity and for identification of individuals in Indian goat breeds.
