HETERODUPLEX MOBILITY ASSAYS (HMAS) AND ANALOGOUS SEQUENCE-ANALYSIS OF A CYTOCHROME-B REGION INDICATE PHYLOGENETIC-RELATIONSHIPS OF SELECTED CALLITRICHIDS

Heteroduplex mobility assays (HMAs) of a cytochrome b region were used for estimating genetic distances and phylogenetic relationships betwe en some selected neotropical primates of the families Callitrichidae ( marmosets and tamarins) and Cebidae [capuchin monkey, (Cebus apella)], and man (Homo sapiens). HMA distances were found to be strongly corre lated to analogous estimates derived from DNA sequence data, Phylogene tic trees obtained by HMAs and sequence analyses showed similar topolo gies with almost identical intraspecific, intrageneric, and intergener ic relationships, The applicability of HMAs is assessed relative to di fferent levels of molecular and organismal diversity.
