Abstract
A variance component analysis of the distribution of serum pepsinogen I levels in normal individuals is reported, using a maximum-likelihood method on entire pedigrees. A broad heritability of 91% is indicated, with some 74% being attributed to a dominance component. Apparently, the pepsinogen I level in normals is principally determined by the action of major genes, as also seems to be the case for duodenal ulcer patients and families.
