Abstract

PENA-CRUZ, Andrés F et al. Genetic Analysis of the Cat Population of North and South of Cali, Colombia. Acta biol.Colomb. [online]. 2015, vol.20, n.1, pp.109-116. ISSN 0120-548X.  https://doi.org/10.15446/abc.v20n1.41610.

The coat genetic markers and skeleton abnormalities have allowed characterize the profile from more than 400 domestic cat populations around the world. 15 years ago, that profile was established in the city of Cali (Colombia). In this study it was determined if north and south of the city are subpopulations and it was compared the total profile against past study. A decrease in allele frequency of a (non-agouti) and d (dilution) was found, but an increase of five alleles was found, especially in l (long hair) and c^s (siamese). These differences could be attributed to human selection of more attractive characteristics and gene flow resulting from demographic growth city, which would also explain the first report of inhibitor and ticked abyssinian alleles. Hardy-Weinberg equilibrium was evaluated for the north, south and both areas together, using white spotting and orange loci, determining disequilibrium in orange for the three evaluated areas due to a heterozygotes deficit. North and south were divided into two, each sub-sample showed Hardy-Weinberg equilibrium, although allele frequencies and heterozygosities highlighted microgeographic structure and a relationship between founding time of the neighborhood and heterozygosity. North and south are a single population and aren´t subpopulations (F_ST= 0,0004, D= 0,0017), as well as nine Colombian populations with which this city was compared. It is suggested to make a microgeographical gene flow analysis and the definition of possible cat colonies in Cali.
