Claytonia virginica is a woodland spring herb with flowers that vary from white to pale pink to bright pink. You are running two separate breeding experiments to select for bright pink flower color. In your lab population A, the selection gradient is 0.9 and the variance in flower color, as measured by hue, is 8 degrees. In lab population B, the selection gradient is 0.5 and the variance in flower color is 7 degrees. Given these data and assuming narrow-sense heritability is the same for all of your breeding experiments, how will the evolutionary response to selection differ between the two lab populations?
