Question

In Wisconsin, a very large population of lake trout, in which individuals mate at random, experiences no migration, mutations, nor selective pressure for a number of years. Which of these is most likely to occur in the population?

Answer 1

In this population, what will occur is that there will be no evolution. Mutation is neccessary and important because they provide varitations that can result in evolutionary change. Other factors needed for evolution to occur are migration and selective pressure.
