GENE SEGREGATION AT THEF-VANDTf-LOCI IN SOME CATTLE BREEDS

Abstract

In the F-V system a deviation was found from material does not permit a detailed study of the expected ratios resulting in an increase possible causes. There was no indication of of the frequency of the gene for the blood-a mother-fetus incompatibility with respect to group F in the offspring, in three of the four the ff types in this material.breeds studied. The explanation that this is
