Objectives.

Establish the genetic profiles of cats from 12 neighboring municipalities in southwestern Colombia, in a town course from Pereira-Popayán. Estimate the degree of diversity, genetic structure, and quantify gene flow.

Materials and methods.

Were inventoried the phenotypic markers present in the pigmentation and structure of the coat of 1482 cats of the municipalities surveyed. Based on these phenotypic frequencies, allele frequencies, heterozygosity, Hardy-Weinberg equilibrium, F statistics and Nei genetic distances were calculated. A comparison was also made between genetic and geographic distance matrices to determine if there was a significant association between the two.

Results.

With the genetic profiles of the populations we estimated the degree of diversity. We found the populations in equilibrium for the S autosomal locus and for the O sex-linked locus. We found a low level genetic structure, and it was determined that there was no significant correlation between the genetic and geographic distance matrices among populations.

Conclusions:

These findings can be explained on the basis of the processes of human displacement for this region, due to the fact that the establishment of feline populations in these municipalities originated during the same historical period. Identical genetic profiles are shared as a result of colonization events, and due to possible continued migration among these populations.
