Esterase D in Brazilian Saguinus midas niger—results and comparison with previous studies in Anthropoidea

Abstract
Four esterase D (ESD) phenotypes, presumably resulting from the segregation of three alleles with moderate polymorphic frequencies, were observed in a sample of the black handed tamarin, Saguinus midas niger, from the northern Amazonian region (Brazil). Previous surveys in the non‐human Anthropoidea indicate that the ESD locus is polymorphic in at least 4 of the 19 taxonomic entities listed.
