Evidence for the presence of an additional allele in the F system of British Friesian cattle blood.
The antithetical relationship of the F and V alleles in British Friesian cattle was found to be imperfect. The presence of another allele was inferred. It was suspected of being native to the British Isles. Parentage records that contravened the assumption that F + V -- and F--V + animals were homozygous were not necessarily erroneous. Black and white cattle in the Netherlands have received semen from a bull carrying the allele.
