Estimates of heritability in weight and length/height in the Netherlands Twin Register study, with data from another study of late pregnancy added. Heritability of weight declines from ∼50% at 25 weeks gestation to ∼30% at birth, then increases to ∼70% by 36 months. The post-natal pattern for length is very similar. Data from Gielen et al. [29] and Mook-Kanamori et al. [30]. Reprinted with permission from Ref. [39]
