• Genetic characterization of five asinine populations, corresponding to two Brazilian breeds (Nordestina - two populations - and Marchador Brasileiro), a local breed of Portugal (Burro de Miranda) and a diverse group of individuals from different Iberian populations was performed based on 193 animals. Fifteen microsatellites markers were analyzed in order to estimate the inter/intra population variability as well as to know the genetic relationship between Brazilian and Iberian asses. The results showed that the majority of loci were not at Hardy-Weinberg equilibrium in the investigated populations due to a significant excess of homozygotes (P
