For a diallelic autosomal character, the correlation between parental total score and offspring total score (known as the parent-offspring correlation) given by + √{s(1 + 3F)/[(s + 1) + F(3s − 1)]}, is used here to estimate F, the constant which is commonly interpreted as coefficient of inbreeding. When the family records include varying number of children, a reasonably good estimate of F is exhibited which agrees fairly with other available estimates.
