DNA-estimated heritabilities increased from 0.26 at age 7 to 0.45 at age 12; twin-estimated heritabilities also increased from 0.35 to 0.48.

Heritabilities for the slope and the quadratic term are based on terms from QTL models (3) and (4), respectively.

Heritability ratios are considered from observations on genotypes grown in a series of environments, sampling sites, and years. Two random models, appropriate to randomised complete block designs, are ...
