1.)Which of the following explains why genetic variation is necessary for evolution to occur in a population ?
-A.) Without genetic Variation, alleles in population would cross over twice so that the DNA would remain the same in population, and evolution would not occur.
-B.)without genetic variation, asexually-reproducing organisms could not mate and their species would die out.
-C.) Without genetic variation, DNA would stay the same from generation to generation, preventing the process of evolution.
-D.) without genetic variation, mutation would occur, wiping out entire population's before they could evolve.

2.) For The Hardy-Weinberg Principle to be true, 5 conditions must be met. Which of the following are not one of these conditions?
-A.) No mutation can occur. -B.) No gene flow can occur. -C.) No genetic drift may occur. Or -D.) No random mating can occur.
