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.
