Figure 1From: Genetic architecture of body size in mammalsSelection experiments with domestic species indicate many genes underlie variation in body size. (a) Angus cattle [35] and (b) mice [36] from long-term selection experiments for high and low growth show phenotypes outside the normal range of the unselected population. The photographs were kindly supplied by Robert Herd (NSW Department of Primary Industries, NSW, Australia) and Lutz Bünger (University of Edinburgh, Edinburgh, UK).
