Chromosome Studies of Primates

II. Callithrix, Leontocebus and Callimico

Abstract

Chromosome numbers were determined for the platyrrhine genera Callithrix (2n=46), Leontocebus (2n=46), and Callimico (2n=48). The karyotypes of the two marmoset genera are virtually identical. It is suggested that the marmosets are specialized for their mode of existence, rather than truly primitive.
