| Abstract: | Four additional cattle blood group antigenic factors, provisionally termed Fl, F6, F10 and F15, were shown to belong to the C system. Factor Fl appears to be a linear subtype of C(initially designated F2, or P1B1). It is suggested that future international nomenclature should adopt C, and C2 in place of Fl and C . No phenogroup was found to include C together with C2 or C1, but a few phenogroups lack the three factors. Thus C1, C2 and Cdo not form a closed system within the C system as concluded by Duniec et al. (1973). The effectiveness of the additional factors to uncover the genetic variability of the C system, and to translate phenotypes into genotypes is exemplified in the Charolais breed. |
