Abstract
Previous paper reported that guinea fowl red blood cells were clasified into two types by normal chicken serum (anti-Gf); Gf possitive (Gf-group) and Gf negative (gf-group).
The present experiments were performed to detect Gf antigen in red blood cells obtained from guinea fowl-chicken hybrids. Gf antigen was recognized in red blood cells from the hybrids. Hybrid red blood cells could be classified into two groups, possitive group and negative group. Frequency of Gf antigen in red blood cells from 50 hybrids was as follows: possitive group, 17 hybrids (34.0%); negative group, 33 hybrids (66.0%). Serological structure of the Gf antigen was divided into GfI and GfII partial antigens, GfI antigen was recognized in the guinea fowl only, whereas GfII was recognized in both the guinea fowl and the guinea fowl-chicken hybrids.
