Evolution Wi(Re)…s: A comprehensive review of Evolution
1. The pollutants associated with the Industrial Revolution caused
a. Light-colored moths to have a selective advantage over dark-colored moths
b. Light-colored moths to become less camouflaged in their natural environment and this
increased bird predation of light-colored moths
c. Black-colored moths to survive better on light-colored tree trunks
d. Light-colored moths to evolve into dark-colored moths
2. A population consisting of green-eyed and red-eyed fruit flies occupying the same region race a cold,
harsh winter and none of the green-eyed fruit flies survive. Consequently, the frequency of the allele
for green eyes becomes zero. This is an example of
a. Genetic bottleneck
b. Founder effect
c. Mutation
d. Random mating

5. Which of the following conditions must be maintained for a population to be in Hardy-Weinberg
equilibrium?

b. Breeding population must be small
c. Breeding population must be large
d. Many mutations
6. Which statement about a mechanism of speciation is INCORRECT?
a. Sympatric speciation occurs within a population and without geographical isolation

groups from the parent population
c. Sympatric speciation is rare in plants, but not in animals
d. Allopatric speciation occurs through colonization
7. In a large population of monarch butterflies, the frequency of the homozygous dominant phenotype
for wing patterns is 0.25; the recessive phenotype frequency if 0.35. After four randomly-mating
generations, the new phenotype frequencies are 0.5 for homozygous dominant and0.45 for
recessive. This is evidence of
a. Directional selection
