Results from the genotypic divergence and plasticity experiment. (a) MANCOVA model using shape variables (n = 11) as dependent variables, (b) ANCOVA model using parents as a random factor and the population divergence vector as the dependant variable, and (c) ANCOVA model using parents as a random factor and the predator divergence vector as the dependent variable
