Consider a population of snails in which individuals have either blue or yellow shells. Snail shell colour is heritable and determined by the colour of the shells of their parents. Yellow snails can better camouflage themselves to hide from predators against a yellow background, while blue snails can better camouflage themselves against a blue background. Under normal circumstances, both yellow and blue coloured backgrounds exist in the snails' habitat. Do you think natural selection will occur in this population? Explain why or why not, and be sure to mention how this scenario relates to the requirements for natural selection to occur. Format BIU www Ea
