Abstract
The objective of the research was to determine the genetic variability of the domestic cat Felis catus using ten genetic markers of hair coat in 13 subpopulations of the department of Sucre. A total of 1548 cats were genotyped for ten dominant hair markers in 13 subpopulations of Sucre. Allele frequencies per loci, percentage of polymorphic loci (%P) and expected heterozygosity (He) were estimated for each subpopulation. Hardy-Weinberg equilibrium (EHW) was calculated for the orange and spotted white loci. An analysis of molecular variance (AMOVA) was performed between subpopulations, estimating the coefficient of genetic differentiation (FST). A matrix of FST and geographic distances was constructed for the Mantel test. The GST (gene differentiation coefficient) was estimated from similar reports in 31 municipalities and 15 departments. The highest allelic frequency was at the spotted white locus and the lowest at the Abyssinian locus. Genetic diversity was moderate, with the lowest diversity found at the Abyssinian and Siamese loci. The most diverse loci were Inhibitor and Orange. Likewise, the most and least diverse subpopulations according to He and %P were Sincelejo and Buenavista, respectively. The dendrograms suggest that there is no population structure and that gene flow is high. In conclusions, the domestic cat of the department of Sucre has high genetic diversity, low population structure and high gene flow.
