Q: A cat needs only one copy of the normal allele to synthesize enough tyrosine to make black
fur. True or False?
A: True ✔✔ (The F1 generation is 100% black, which means heterozygotes are black despite
only having one normal allele.)
Q: A model is a formal description of a scientific hypothesis. Which of the following types of
models provides the most precise description of a hypothesis?
verbal
graphical
mathematical
All of the above are equally precise
A: mathematical ✔✔
Q: Does a probability of 0.98 mean that an event occurs rarely? True or False?
A: False ✔✔
Q: Does a Punnett square enable one to determine the frequency of observed genotypes without
using a mathematical formula to calculate the joint probability? True or False?
A: True ✔✔
Q: A well-designed experiment ____________.
a. controls for environmental and genetic factors.
b. involves replication of experimental subjects.
c. randomizes experimental subjects among treatments.
, d. achieves all of the above.
A: d. achieves all of the above ✔✔
Q: Does an experiment enable one to demonstrate that a correlation between two variables
results from cause and effect? True or False?
A: True ✔✔
Q: Approximately half of the cats in the F2 generation will have white fur. True or False?
A: True ✔✔ (Since the back parent of the F1 generation is heterozygous, 50% of its offspring
will inherit the mutant allele along with the mutant allele from the white parent.)
Q: Based on the phenotypes of John and his siblings, is the allele for moist ear wax more likely
dominant than recessive? True or False?
A: False ✔✔ (Most of John's family have dry ear wax, which would be more likely if the allele
for moist ear wax were recessive.)
Q: Did biologists use induction to hypothesize that snakes use pits to see heat? True or False?
A: True ✔✔
Q: Did biologists use induction to predict the percentage of times that snakes with sealed pits
would choose the cool box? True or False?
A: False ✔✔
Q: Must both Darwin and Wallace have assumed that differences among individuals were passed
onto their offspring? True or False?
A: True ✔✔
Q: Did both Wallace and Darwin adopt a worldview described as either naturalistic evolution or
theistic evolution? True or False?
A: True ✔✔
