Description of the cytochrome c oxidase subunit II gene in some genera of New World monkeys (primates, Platyrrhini)

Nucleotide sequence variation at the mitochondrial cytochrome c oxidase subunit II gene (COII) was analyzed in 27 New World monkey specimens, nine newly reported herein. The study involved comparisons among platyrrhines and also between platyrrhines and catarrhines. The analysis of the frequencies o...
