ResumenEn varios estudios se ha sugerido que variables como la intervención humana y el tiempo no generan cambios estadísticamente significativos en los perfiles genéticos de las poblaciones del gato doméstico, lo cual explicaría por qué la mayoría se encuentra en panmixia. Sin embargo, en pocos estudios se ha determinado el perfil genético de ciertas poblaciones más de dos veces en un lapso de varios años, por lo que no hay argumentos suficientes para concluir que el tiempo no afecta significativamente los perfiles de las poblaciones. Además, debe mencionarse que existen diferentes procesos estocásticos que actúan sobre cada uno de ellos. Ahora bien, la ciudad de Cali, Colombia, es una de las pocas en Latinoamérica en donde se ha establecido el perfil genético de los gatos en varias ocasiones (1999 y 2012). En el presente estudio se hizo un muestreo para establecer el perfil genético de dicha población durante el 2015. Se hicieron comparaciones mediante pruebas de chi cuadrado entre los periodos mencionados Vs. 2012 Vs. 2015 y 2012 Vs. 2015, y se estableció que no hubo cambios estadísticamente significativos entre ellos, aunque se registraron variaciones considerables en las frecuencias de los alelos White Spotting (S) y siamese (c s ). Por otro lado, el árbol de distancias genéticas dendograma demostró que los perfiles de los años 2012 y 2015 fueron más similares en comparación con el de 1999. En este contexto, se sugiere que los efectos estocásticos, así como los de la selección humana y el factor tiempo son despreciables. © 2017. Acad. Colomb. Cienc. Ex. Fis. Nat.

Temporal differentiation of the genetic profiles of the cat population in Cali, Colombia, during the last decades AbstractSeveral studies have suggested that variables such as human intervention and time do not generate statistically significant changes in the genetic profiles of domestic cat populations, which would explain why most are in panmixia. However, few studies have determined the genetic profile of certain populations more than twice over a period of several years, so there is insufficient evidence to conclude that time does not affected population profiles significantly. Also, it should be mentioned that there are different stochastic processes acting on each of these. The city of Cali, Colombia, is one of the few Latin American cat populations whose genetic profile has been established on several occasions (1999 and 2012). Therefore, in the present study we conducted a sampling to establish the genetic profile of this population during 2015. We compared the above-mentioned periods through chi-square tests, and we established that there were no statistically significant changes among them. However, there were considerable variations in the allele frequencies of White Spotting (S) and siamese (c s ). On the other hand, the genetic distances tree dendogram showed that 2012 and 2015 profiles were more similar than the 1999 profile. In this context, it i...

Considering of multiples research of genetic in cats, the objective of this study was to compare the genetic diversity of the domestic cat population at different spatial and temporal scales. According to the administrative division of the city of Cali, 8 colonies (localities) were chosen, which together form 5 subpopulations within the city for sampling. The phenotype from each individual?s coat was recognized for the subsequent calculation of allele frequencies, Hardy-Weinberg (HW) equilibrium, genetic structure, and correlated genetic diversity and structure with antiquity in each neighborhood. The non-agouti allele obtained the highest frequencies, and the white allele had the lowest frequencies in all colonies and subpopulations; the manx allele was also reported. HW equilibrium was found in the orange locus, except for the Salomia, Sena and Santa Barbara colonies of the NW subpopulation. A significant association was found between the diversity of the tabby locus and antiquity and the differentiation of the colonies (FCT) with antiquity of colonies. In conclusion, domestic cats in the city of Cali behave as a single population, with incipient genetic microstructure phenomena, which are part of the natural dynamics of the population in their interaction with the urban environment.
