You collect observations of red deer within a generation, recording each individual's phenotypes for a number of traits which are known to have additive genetic variation. You also count the number of offspring per individual (a measurement of fitness). Using your data, you construct the plots shown in the figures below (standardizing the phenotypes). Answer the following questions, and briefly justify each of your answers with reference to the breeder's equation and/or multi-trait breeder's equation.

(Write 1-2 sentences explaining your answer.) b) Looking only at the relationship between female leg length and number of offspring (middle graph), in what direction do you expect leg length to evolve (increase or decrease)? (Write 1-2 sentences explaining your answer.) c) Considering the relationship between antler size and leg length in half-siblings (right graph), how might your prediction about the evolution of antler size (from part a) change? (Write 1-2 sentences explaining your answer.)
