Abstract

This study identifies genetic differences that distinguish one breed from another within white skinned pig populations. The Number of alleles (Na) total means was 3.48±0.26. The Landrace had the highest number of allele (Na) 4.00±0.54 among the 3 populations while the Large White had the least 3.14±0.51. The mean of Observed heterozygosities (Ho) of Crosses was highest (0.69±0.11) among the three while they all had the same expected heterozygosities (He) of 0.55.  The means of Frr (measure of the deviation from the Hardy-Weinberg in the total population) and FST (measures of the genetic differentiation over subpopulations) among the markers were  0.06±0.11 and 0.04±0.01, respectively. FIT value was the highest for SW632 (0.41), while it was the lowest for SW226 (-0.05). The phylogenetic tree the three pig populations originated from the same ancestor and branched into two where Landrace and Crosses clustered together while the Large White clustered alone. This study helps to distinguish between the pig breeds and revealed their genetic makeup and identity.
