Animals and samples Blood samples were collected from sheep of the following Colombian breeds: Blood samples were collected from sheep of the following Colombian breeds: The OH ranged between 0. In conclusion, all three Colombian sheep breeds showed high genetic variability, evidenced by high polymorphism and number of alleles per locus for the molecular markers used for genotyping. Microsatellite molecular markers have been extensively used with this purpose by consanginidad authors Kugonza et al.

Parameters evaluating population genetic variability by locus are consangkinidad in Table 2. In general, all breeds showed high genetic diversity. According with the method proposed by Evanno et al.

However, a heterozygosity deficit was present to some extent in all breeds, something mainly attributed to endogamy within sheep flocks.

There was no clear differentiation between populations under any of the K values tested Figure 2which indicates high admixture levels. Anim Gen Resources ; On the other hand, the use of only a few genetic superior males for intensive mating might cause a reduction of the effective population size, higher levels of inbreeding and finally, decreased genetic diversity within breeds Pastrana et al.

Genetic characterization of Colombian indigenous sheep 1. This could be considered as a phenomenon of introgressive hybridization in ovihos there is a gene flow from one population into the gene pool consannguinidad another, but in this case, this introgression would occur between different proportions of the genetic material of three ancestral breeds, as showed by the most likely K value.

Peakall R, Smouse P. Sheep farming represents a profitable production system in Colombia due to the favorable conditions of the market, in which the demand for products from these animals has increased over time. European breeds introduced to the region long after the conquest times with the aim of genetically improving wool sheep could make up the third ancestral group.

African sheep brought to America after the colonization would make up the second ancestral population, and from which breeds like Consanguibidad, Black Belly, and Pelibuey would be descendants.

However, inbreeding of indigenous sheep populations has increased in Colombia due to indiscriminate cross-breeding with foreign animals and consangjinidad of reproductive controls, with subsequent loss in productivity, which poses a great risk for the conservation of valuable genes.
