A family is presented in which the propositus and 2 siblings, apparently
in group O, have in their sera anti-H in addition to anti-A and anti-B. Inspection
of the family tree reveals apparent violations of Mendelian heredity which can
be explained on the basis of a rare suppressor gene which in the homozygote state
suppresses in the propositus the actions of gene B and secretion gene Se. The genes
B and Se are fully expressed when transmitted to her offspring who are heterozygous for the suppression gene.
The same mechanism may be assumed to operate in the 9 other so-called group
O bloods containing anti-H.
