FURTHER DIVISION OF CONTRASTING ANTIGENS IN SPECIES HYBRIDS IN DUCKS

Abstract

VIDENCE for the existence of antigenic differences in the red blood cells E of two species of ducks, Muscovy (Cairina moschata) and Mallard (Anas Platyrhynchos platyrhynchos), and their hybrid has been presented in a previous report It was found that each species possessed antigens specific to itself as well as others common to both. The cells of the hybrids, except for individual differences, contained the major portion of the antigens present in the parental species and, in addition, a new or "hybrid" substance not found in either parent. By appropriate tests, the cells of the three kinds of ducks could be readily distinguished.
