The combined paternity exclusion probability was very high, and the probability of identity was extremely low. Nine loci significantly deviated from Hardy-Weinberg equilibrium after Bonferroni correction (likely due to null alleles) and no significant linkage disequilibrium between loci pairs was detected. The observed and expected heterozygosities for Aa ranged from 0.27 to 1.00 and from 0.35 to 0.94, with averages of 0.75 and 0.85, respectively. Twenty-four and 25 loci were successfully amplified for Av and Ap, respectively. The number of alleles per locus for Aa ranged from 5 to 24 with an average of 13.1.
Loci were tested in 24 Blue-fronted Amazons from wild population from central Brazil with cross-species amplified in two individuals of Amazona vinacea (Av) and Amazona pretrei (Ap) from northeastern Minas Gerais and Rio Grande do Sul, in southeastern and south of Brazil, respectively. In this study, 25 polymorphic microsatellite loci were identified in silico and characterized for the Blue-fronted Amazon. Population genetic studies and effective control of commercial breeders are important actions for the conservation of these parrot species however, few microsatellite loci are available for most Amazona species to date. Parrots are among the most threatened avian groups of the world, with illegal pet trade being a major threat to some Amazon (Amazona genus) and macaw (Ara and Anodorhynchus genera) species.
