Assessment of genetic diversity was carried out in Doom pig using 22 microsatellite markers, recommended by Food and Agriculture Organization (FAO). All the studied loci were highly polymorphic and a total of 120 alleles were observed across the investigated loci. The range of alleles was found to be 4 to 10 with a mean of 5.4±1.65. The frequency distribution of microsatellite alleles in the population was from 0.02 to 0.6667. The observed and expected heterozygosity values were 0.62±0.287 and 0.67±0.142, respectively. The polymorphic information content (PIC) was 0.63±0.143. Microsatellite analysis revealed moderate to less genetic diversity in the Doom pig population. The overall mean of within-population inbreeding estimate (FIS) was 0.089. The Shannon’s information index (I) was sufficiently high with a mean of 1.36. The bottleneck analysis revealed that population has not undergone any recent reduction.
Key words: Heterozygosity, microsatellites, polymorphic information content (PIC), bottleneck, doom pig.
