The aim of this work was to determine the diversity and genetic structure of domestic cat (Felis catus) populations by fur genes in Cartagena, Colombia. We established the phenotype of 472 cats through direct observations in Cartagena's urban area using the nomenclature recommended by the Committee on Standardized Genetic Nomenclature for Cats (1968) for the phenotype markers Orange, Agouti, Tabby, Dilution, Long hair, Spotting white y Dominant white. We determined the allelic frequencies, the genetic diversity, the gene flow, the Hardy-Weinberg equilibrium, and we inferred the phylogenetic relationships. The non-Agouti marker was the most frequent, while Tabby blotched and Dominant white had the lowest values. We reported the presence of the Tabby abissynian allele in Cartagena. Most of the genetic diversity was found within populations () and few between populations (), and we observed a high gene flow and an excess of heterozygotes in the population; there was no Hardy-Weinberg equilibrium. Populations were genetically correlated, and there was evidence of a possible natural and artificial selection of the non-Agouti and Tabby abissynian markers.

Palabras clave : Felis catus; phenotypic markers; diversity, heterozygosity.
