In a population of beetles, about 1 in every 6 beetles is slightly smaller and lighter in color than the others. the small, lighter beetles are a little better at evading predators and this increases the chances of survival and reproduction. what is likely to happen to the representation of the smaller, lighter beetle in the overall population over time? will the ration remain at roughly 6: 1, or will it change? if it changes, why will it change, and in what direction?
