COII: A useful tool for inferring phylogenetic relationships among New World monkeys (Primates, Platyrrhini)

In this study we evaluated the performance of the cytochrome c oxidase subunit II (COII) mitochondrial gene as a tool for inferring phylogenetic relationships among platyrrhines. Twenty-nine COII sequences were examined in seven platyrrhine genera (Alouatta, Ateles, Lagothrix, Brachyteles, Cebus, Sa...
