^aAverage genotypic value at G7. ^bResponse to selection as estimated using (3). Significance is indicated (*** = p < 0.001, ns = non significant). ^cstandard error of R. Heritabilities are computed from the average response to selection as the ratio of the additive genetic variance to the residual variance by using an EM algorithm (11 and 9). In parentheses are the 95% confidence intervals that were simulated by taking into account uncertainty in the estimated response to selection and in the residual variance, (see Material and Methods). Genetic variance is assumed to come either from new mutations (Model 1, = 0) or from standing variation (Model 2, = 0) or else from both (Model 3). In Model 3, the value for corresponds to the minimum value which gives a non zero estimate of the mutational heritability.
