Sib correlations for height and weight decrease with absolute age difference. Parent child correlations increase with age of child, with greater resemblance to the mother than the father. Estimates of the relative variance due to common environment are greater, and heritability estimates less, than for earlier studies. Heritability is less for adults than children. There is no significant major locus for height or weight.
