Relationship between predicted mean of litter size on the observable scale (Mean obs.) and predicted variance (Variance obs.) for each genotype according to the mean of the underlying variable†. † Predicted mean and variance of litter size on the observable scale were calculated for each genotype by combining the specific set of thresholds {τ++} and {τL+} with an underlying variable Ν(η, 1) for which the mean η varied from -1 to +1. Plain markers correspond to the underlying variable Ν(0, 1) of the output of the threshold model.
