The genetic diversity and structure of four populations of Large White breed pigs grown in various breeding farms in Ukraine, using 12 microsatellite DNA loci (SW24, S0155, SW72, SW951, S0386, S0355, SW240, SW857, SW0101, SW936, SW911 and S0228) were studied. When analyzing intra- and inter-group variability, 158 alleles of the 12 analyzed loci were identified. The total number (Na) and effective number (Ae) of alleles varied from 6.25 (Na) and 3.40 (Ae) to 10.25 (Na) and 5.63 (Ae) alleles per locus. The Hardy-Weinberg equilibrium test (HWE) showed that all of the polymorphic loci deviated from HWE (p < 0.05) in at least one population. The Analysis of Molecular Variance (AMOVA) showed that 12.2% of the total genotypic variation was due to differences between populations. Wright’s fixation index (Fst) per locus varied from 0.037 (SW72) to 0.581 (SW911), with a mean value of 0.148 ± 0.049. The mean Fis and Fit values for all loci were 0.163 ± 0.026 and 0.287 ± 0.047, respectively. The positive Fis value for all loci in the studied populations probably reflects the division of the general population in subpopulations due to the inbreeding accumulated in small groups of individuals. |
