Question 1
Your answer is CORRECT.
What is evolution?
a) Change in the phenotypes of individuals in a population during reproduction.
b) Frequent changes in allele frequencies that occur within a single generation.
c) Developmental changes that occur within a population resulting in phenotypic differences among offspring.
d) Any change in the heritable traits within a population across generations.
e) All of the above
Question 2
Your answer is CORRECT.
Which of the following must occur, or must have occurred at some point, in order for evolution by natural
selection to take place?
a) Mutation
b) Homology
c) Genetic drift
d) Sexual reproduction
Question 3
Your answer is CORRECT.
One proposed resolution to the C-value paradox of genome size is that genome size is a consequence of the
interaction of genetic drift and natural selection. Which of the following statements best describes this
hypothesis?
a) Changes in genome size are neutral and therefore their fixation in a population is determined by genetic
drift. Since genetic drift is stronger in smaller populations, organisms with small population sizes will have larger
genome sizes.
b) Mutations that increase genome size are slightly deleterious and can only be eliminated from species with
large population sizes. Thus, genome size is largely determined by population size.
, c) Natural selection cannot act on genome size because genome size is not a trait with heritable genetic
variation. Thus, it is primarily determined by genetic drift.
d) Increases in genome size are beneficial because they can result in new genes. Thus, species that have high
beneficial mutation rates will have the largest genome sizes.
e) None of the above are reasonable hypotheses to explain the C-value paradox.
Question 4
Your answer is CORRECT.
Based on the phylogeny below, which of the following two groups are most closely related?
a) Turtles and snakes
b) Ray-finned fishes and lobe-finned fishes
c) Birds and crocodilians
d) Mammals and snakes
e) None of the pairs above are related.
Question 5
Your answer is CORRECT.
