Figure 5
21) Before the Industrial Revolution most peppered moths were white with a few black spots. A
mutation occurred in some and the offspring had many more black spots than others. Usually the ones
with more black spots were eaten.... they didn't blend in. But as the Industrial Revolution grew in
England pollution began to darken (buildings, fences, rocks, etc.) Reference figure 5
a. Predict which form of moth has the highest survival rate. Black Peppered or White Peppered
Answer: Black Peppered
b. Was the mutation beneficial, harmful or neutral to the moth with the highest survival rate?
Answer: beneficial
FYI for the teacher: The white moth was highly visible and eaten more often than the less white w/
many black spots. The more black-spotted moth survived to reproduce. Eventually the population of
peppered moths was all dark with only a few spots of white. That is evolution due to a mutation that
became beneficial because of a change in the environment.
22) One difference between a gene mutation and a chromosomal mutation is that
a. A gene mutation affects the DNA of more genes than a chromosomal mutation.
b. A gene mutation can involve a insertion or deletion, but cannot result in a frameshift.
c. A chromosomal mutation can change the number of chromosomes in a cell.
d. A chromosomal mutation is more likely to be passed on to offspring or daughter cells.
23) A possible mutagen is
a. an anticodon
b. translocation
c. hemoglobin
d. ultraviolet light
24) In gene therapy,
a. mutations are caused to increase genetic variation
b. DNA is cut with restriction enzymes
c. transgenic organisms are produced
d. a faulty gene is replaced by a normal, working gene
25) What happens when a cell cannot repair the damage caused by a mutagen?
a. The DNA base sequence changes permanently
b. The DNA base sequence is not affected.
c. The organism is not affected.
d. The organism is affected temporarily
26) Mutations are important to the evolution of a species because they
a. happen over the long period of time that evolution requires
