4. Seed production in the daisy species can depend on size of the flower by attracting pollinators. In one habitat, the average diameter of the flower disc for a daisy species is \( 24 \mathrm{~mm} \). a) In one year, the variance of flower diameters in the population is \( 25 \mathrm{~mm}^{2} \), selection gradient of seed sets vs flower diameter is \( +0.18 / \mathrm{mm} \), and the narrow-sense heritability is \( 0.42 \). What is the evolutionary response and the average diameter of flowers in the next generation (annual plant)? b) In the second year, the variance of flowers in the population is \( 16 \mathrm{~mm}^{2} \), selection gradient of seed sets vs. flower diameter is \( -0.09 / \mathrm{mm} \), and the narrow-sense heritability is \( 0.35 \). What is the evolutionary response and the average diameter of flowers in the next generation?
