Abstract
The genes involved in cat coat traits are useful for the analysis of genetic structure within a population. The objective of this paper was to determine if any genetic differences exist among domestic cat populations from the municipalities of Restrepo and Darien, which are separated by Calima Lake. To analyze population structure, we estimated allelic frequencies of several coat markers, tested for alignment with the Hardy-Weinberg equilibrium, and compared our populations of interest to others from the Valle del Cauca region. Subsequently, we performed a principal components analysis (PCA-Biplot) to determine the correlation between allelic frequencies and their contributions to variability. A Mantel test was also used to estimate possible correlation among differentiation indexes (FST) and geographic distances. We performed the Mantel test on the Orange gene and identifi ed a positive correlation among differentiation indexes (FST) and geographical distances. After comparing our populations of interest to others in the Valle del Cauca, we observed that the genes with the greatest contribution to variability were Dilution (19,08%), Long hair (16,09%), Agouti (16,06%) and Inhibitor (14,04%). However, we also found that the Restrepo and Darien populations of interest had similar genetic profi les, and aligned with the Hardy-Weinberg equilibrium, and the FST. Due to the absence of signifi cant differentiation between the populations studied, we conclude that Calima Lake does not have a signifi cant effect on any differentiation between the cat
populations of Restrepo and Darien.
