Molecular characterization of Ghungroo pig
Pages : 1-4
Ghungroo pig is indigenous to West Bengal and has already made in road to NE India for its high productivity. A total of 21 microsatellite markers were used to study genetic diversity and population structure of Ghungroo pig. All the considered loci were highly polymorphic and a total of 103 alleles were observed across the studied loci. The range of alleles was found to be 2 to 9 with a mean of 4.9±2.567. The frequency distribution of microsatellite alleles in the population was from 0.0179 to 0.9615. The calculated observed and expected heterozygosity values were 0.55±0.356 and 0.58±0.216 respectively. The PIC was 0.54±0.22 and Shannon’s information index was sufficiently high with a mean of 1.16. The overall mean of within-population inbreeding estimate (FIS) was 0.0919. The bottleneck analysis revealed that population has not undergone any recent reduction.
