  1. NS: not significantly different from a Gaussian distribution at P = 0.05; *, ** and ***: significantly different from a Gaussian distribution at 0.05, 0.01 and 0.001 probability levels, respectively. P1: parent 1, P2: parent 2, |P1-P2|: absolute difference in trait value between two parents of a cross, S: skewness, K: kurtosis.
