title: Note on a third allele in the erythrocytic NP system of cattle.
abstract: A bull ('Mercure') with an erythrocytic NP (nucleoside phosphorylase), phenotype showing a slightly higher anodal mobility has been found. His progeny data generally support the hypothesis of a third F allele in addition to the more common S and the L alleles, resulting in an ABO-like system.
