Hemoglobin Polymorphism in Chimpanzees and Gibbons

Abstract
Hemoglobin polymorphism has been observed in the chimpanzee and two subspecies of gibbons. In chimpanzees, hemoglobins J and B were found in addition to hemoglobin A; J and B differed from A in their alpha and beta chains, respectively. Hemoglobins A and B were observed in different subspecies of gibbons; B differed from A in its beta chain.
