QUESTION 1 In some species of fish, a forked tail fin is dominant to a continuous tail fin. Fish with either fin type swim equally well. The frequency of individuals in a fish farm population that have the continuous tail fin is 49%. Assume the population is in Hardy-Weinberg equilibrium for this trait. What is the frequency of the continuous tail fin allele in this population? O a. 0.3 O b.0.7 O c. 0.2 O d. 0.9 O e.0.8

QUESTION 1
In some species of fish, a forked tail fin is dominant to a continuous tail fin. Fish with either fin type swim equally well. The frequency of individuals in a fish farm population that have
the continuous tail fin is 49%. Assume the population is in Hardy-Weinberg equilibrium for this trait.
What is the frequency of the continuous tail fin allele in this population?
O a. 0.3
O b.0.7
O c. 0.2
O d. 0.9
Oe. 0.8
QUESTION 2
When a population is in Hardy-Weinberg equilibrium, this means
O a. the population might experience migration, drift, mutation or natural selection.
O b. allele frequencies, but not genotype frequencies, can change.
O c. the gene pool will change over time.
O d. the population is large and randomly mating.
O e. individuals do not change over time.
QUESTION 3
An example of a postzygotic reproductive isolating mechanism is
O a. Spiders developing elaborate species specifc courtship dances.
O b. Shoreline birds don't mate with deep forest birds because they occupy different habitats.
Oc. The two organisms can mate but the gametes are unable to fuse
O d. The two organisms can mate but the offspring is infertile
