The aim of this research was to determine the genetic variability of domestic pigeon populations (Columba livia), using genes that encode plumage color in Sincelejo, Sucre (Colombia). The populations, distributed in twenty-four colonies, were studied between July 2016 and January 2017, and included 1402 individuals. The markers were: Plumage pattern, Primary coloration, Spread and Grizzle. The genetic parameters allele frequencies, genetic diversity and population structure were calculated through the program PopGene 1.31, genetic distance was determined by the program FSTAT v. 2.9.3.2, and the dendrogram was carried out using the program Mega 7. The allelic frequencies obtained varied from 0.2290 for the allele Checker (C), 0.1458 for the marker T-Pattern (CT), 0.1317 for the gene Grizzle (G), 0.0882 for the marker Ash-Red (BA) and 0.0282 for the allele Spread (S). The coefficient of ge...

The study was conducted to analyze the genetic diversity of the population of cats (Felis catus) of the Colombian city of Mompox, Bolívar. The following genes were studied: Orange, Agouti, Tabby, Dilution, Long Hair, Spotting White Dominant White, Manx and Siames for 200 cats in five neighborhoods of the city. Mompox presented allelic frequencies that ranged between 0.678 and 0.003 for the Non-agouti and Manx markers, respectively. The Spotting White and Long Hair markers showed the greatest diversity; the Orange marker presented disequilibrium in two populations: Seis de Agosto and Faciolince, while Spotting White maintained a Hardy-Weinberg equilibrium. A high genetic differentiation was found between the populations (GST = 0.1283). In Mompox an association of the populations was presented attending the date of their foundations. In the Colombian Caribbean, the populations were groupe...

Con el objetivo de analizar la diversidad genética de la población de gatos (Felis catus) de la ciudad colombiana de Mompox, Bolívar, se estudiaron los genes: Orange, Agouti, Tabby, Dilution, Long Hair, Spotting White Dominant White, Manx y Siames para 200 gatos en cinco barrios de la ciudad. Mompox presentó frecuencias alélicas que oscilaron entre 0.678 y 0.003 para los marcadores Non-agouti y Manx, respectivamente. Los marcadores Spotting White y Long Hair mostraron la mayor diversidad; el marcador Orange presentó desequilibrio en dos poblaciones: Seis de Agosto y Faciolince, mientras que Spotting White se mantuvo en equilibrio de Hardy-Weinberg. Se halló una alta diferenciación genética entre las poblaciones (GST= 0.1283). En Mompox se presentó una asociación de las poblaciones atendiendo a la fecha de sus fundaciones. En el Caribe colombiano, las poblaciones se agruparon c...
