A study of weight increase in the first year of life has been carried out on a sample of 50 MZ and 50 DZ twin pairs of both sexes, as compared to a similar sample of singletons. The results show that weight increase, as examined at different stages in the first year of life, undergoes significant hereditary conditioning (H ≃ 0.60).
