Evidence from the flour beetle experiments discussed
  in the text provides support for genetic drift resulting
  in
  a. random change in allele frequencies.
  b. fixation of one or more alleles.
  c. loss of genetic diversity.
  d. greater change in allele frequencies in smaller
  populations.
  e. all of these.

Question 2

If you sampled the genetic characteristics of a large
  population and found that of the 50 loci analyzed
  there is very little, if any, variation, the most likely
  explanation is that
  a. a uniform environment selected for these alleles.
  b. there has been a lack of migration, and the
  genetic equilibrium stabilized the population.
  c. strong selection pressures eliminated alternative
  alleles.
  d. a bottleneck effect may have occurred in the past
  to reduce the variability in the population.
  e. a combination of low mutation rates and
  differential sexual selection produced these
  results.
