Se estudió la variabilidad genética de individuos adultos de ambos sexos pertenecientes a dos especies de Platyrrhini. Se analizaron 16 muestras de sangre de Alouatta caraya (ACA) y 12 de Cebus apella paraguayanus (CAP). Se estudiaron 10 sistemas proteicos mediante electroforesis horizontal en geles de poliacrilamida. De 14 loci analizados en A. caraya, solo AMP y TF fueron polimórficos (P = 0.1429; = 0.0359); de los 13 loci estudiados en C. a. paraguayanus, solo ESD fue polimórfico (P = 0.0769; = 0.0062). La distancia genética entre ACA y CAP fue D = 0.5962. Los valores de H y D son discutidos respecto de otros previamente publicados para primates neotropicales.

Protein variability analysis for Alouatta caraya and Cebus apella (Primates: Platyrrhini). The genetic variability of adult individuals of both sexes belonging to two species of Platyrrhini was studied. Sixteen blood samples of Alouatta caraya (ACA) and 12 of Cebus apella paraguayanus (CAP) were analyzed. Ten protein systems were examined by horizontal polyacrilamide gel electrophoresis. Out of 14 loci scored in ACA, only AMP and TF were polymorphic (P = 0.1429; = 0.0359), whereas only ESD was polymorphic in 13 loci studied in CAP (P = 0.0769; = 0.0062). The genetic distance between ACA y CAP was D = 0.5962. Values of H and D are discussed with respect to previous published data on Neotropical primates.
