Bio 204 study questions
1. Evolution is a change in in a(n) over time.
A. Phenotype, Frequency, Population
B. Genotype, Frequency, Population
C. Allele, Frequency, Individual
D. Allele, Expression, Population
E. Allele, Frequency, Environment
F. Allele, Frequency, Population: F. Allele, Frequency, Population
2. Which of the following sets of measurements would NOT allow a researcher
to directly quantify fitness?
A. Litter size & number of litters over a female lion's lifetime
B. Percentage of copulations resulting in paternity & number of copulations &
longevity of a male lion
C. Seed set (number of seeds in a pollinated flower) & number of flowering
,events over a dogwood tree's lifespan
D. Aggressive displays to protect breeding territory & longevity of a male
Eastern bluebird
E. Percentage of mating attempts resulting in paternity & number of mating
events & lifespan of a male Eastern bluebird: D. Aggressive displays to protect breeding territory
& longevity of a male Eastern bluebird
3. 1. A patch of forest in western Virginia is entirely destroyed by a forest fire.
Leg lengths of a population of eastern cottontail rabbits (Sylvilagus floridanus),
which depend on berries within the forest for food, was measured 1 year before
and 2 years after the fire. Those data are shown in this figure (ANOVA p < 0.05).
Which of the following describes a possible mechanism for change in rabbit leg
length via natural selection?
A. This data collection was likely an example of human sampling error. After the
fire, large, long-legged rabbits were more likely to be caught and measured
,than small, short-legged rabbits.
B. Short-legged rabbits are more likely to burrow in times of stress than
, long-legged rabbits, and burrowing is an effective survival strategy during
fast-moving forest fire. Short legged rabbits were able to survive the fire, while
long-legged rabbits were more likely to perish in the blaze.
C. The fire event caused increased cortisol (a stress hormone) levels in rabbits.
Cortisol production is associated with rapid leg growth at all life stages.
D. Long-legged rabbits are more mobile than short-legged rabbits, and in-
creased mobility is associated with increased home range. Long legged rabbits
are able to access berries in a patch of unburned forest 5km from the burned
range while short legged rabbits are more likely to die from starvation.: D.

4. 1Which of the following does NOT describe one of Darwin's postulates for
evolution by natural selection?
A. Tail length of anole lizards is variable within a population.
