  • Additive models correspond to a linear regression under the assumption that the TC heterozygotes class shows no dominance. Arbitrary dominance (AD) equals a standard ANOVA, with no assumption about the degree of dominance. Covariate represents the inclusion of centroid size, which had minimal impact upon the strength of the association between genotype and shape variation. SS, sum of squares; MS, mean square; ProbF, probability of F.
