Zovawk are indigenous pigs of the state of Mizoram, India. The 22 microsatellitemarkers recommended byFood andAgriculturalOrganization of United Nations (FAO) for Swine were used to investigate genetic diversity and population structure. The loci used for investigation are informative. The number of observed alleles (Na) detected ranged from2 to 11,with an overallmean of 5.54±2.558. In total 122 alleles were observed in across loci. The effective number of alleles (Ne) ranged from 1.0444 to 7.4405 with a mean of 2.71±1.472. The frequency of allele values ranged from0.0200 to 0.9783. The PIC value ranged from0 to 0.8489. The overall means for observed (HO) and expected (He) heterozygosities were 0.46±0.252 and 0.54±0.192 respectively. The within breed estimate indicate heterozygosity shortage of 0.1526. The Hardy-Weinberg equilibrium test revealed that 11 loci out of 22 deviated from equilibrium. ShannonÂÂ’s information index (I)was sufficiently highwith amean of1.12.The bottleneck analysis revealed that population has not undergone any recent reduction
