Exercise 2

On figure 21.2 b, draw the relationship between offspring beak depth and parent beak depth, assuming that there is no genetic basis to beak depth in the medium ground finch.
Figure21.2 Evidence that natural selection alters beak shape in the medium ground finch (Geospiza fortis). b. Beak depth is inherited from parents to offspring.
Figure 21.5 Artificial selection can lead to rapid and substantial evolutionary change.
