DNA fingerprinting in three species of neotropical primates.

Abstract

DNA fingerprinting allows the simultaneous detection of a large number of hypervariable loci consisting of highly polymorphic tandem repeat units that are extensively dispersed in the genome. With the 33.6 human minisatellite probe, hypervariable fragments were detected, for the first time, in the genome of three different species of wild-caught neotropical primates: Aotus infulatus, Aotus azarae, and Cebus apella. As in the human, these species were highly polymorphic, showing distinctive, individual-specific patterns. Estimates of relatedness within each group were calculated from interspecific comparisons based on the number of shared fragments between individuals. This work shows that the 33.6 human minisatellite probe can be very useful for increasing our understanding of population dynamics and behavior of these species in their natural habitat. © 1996 Wiley-Liss, Inc.
