Observed response to selection. Average male body weights are plotted for high (top curve) and low (bottom curve) selected lines [33]. After 46 generations of directional selection, the lines differ by around 1600 g. The response to selection in the low line reached a plateau after about 30 generations, probably because of physiological constraints. The four-loci genetic network evidenced in [26] has been represented on the right.
