Genetic variation in domestic pig Sus scrofa domesticapopulations in Cordoba-Colombia based on microsatellitemarkers

Abstract

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