The agglutinin having affinity for cattle red cells was found in Feijao chumbinho lectin. The red cells agglutinated by this lectin were Fc type and those not agglutinated were fc type. The phenotype frequencies of the Fc type were estimated to be 41.75% for Japanese Black cattle and 35.71% for Japanese Brown cattle. The genetic study on the Fc system proved that the inheritance of this system was controlled by a dominant allele at an autosomal locus. The gene frequencies of Fc were 0.237 for Black cattle and 0.197 for Brown cattle. These results provide useful information for the research of individual differences and population genetics.
