MELENDEZ GELVEZ, Iván; PARDO PEREZ, Enrique  and  CAVADIA MARTINEZ, Teodora Inés. Genetic variation in domestic pig Sus scrofa domestica populations in Cordoba-Colombia based on microsatellite markers. Rev. mex. de cienc. pecuarias [online]. 2015, vol.6, n.4, pp.443-452. ISSN 2448-6698.

Genetic variation in three populations of pigs in Cordoba, Colombia was evaluated by 20 microsatellite. All loci studied were polymorphic, with an observed heterozygosis ranging from 0.2 to 84.2 % (mean 68.6 %) and expected heterozygosis ranged from 5.6 to 83.8 % (mean 70.2 %). The polymorphic information content (PIC) value for all markers analyzed ranged from 0.17 (least informative) and 0.83 (the most informative). The level of genetic differentiation FST between pairs of populations varied in the range from 0.07 to 0.11, being statistically significant in all analyzed pairs. In conclusion, the levels of expected heterozygosis found in the present paper show that the domestic pig in Cordoba, exhibits a high degree of genetic variability. Similarly, the genetic identity of Nei and statistical FST indicate genetic closeness between populations Momil and Cereté, which binds Tierralta, indicating migration between these three populations but keeping each its genetic identity.
