BI358 PSU Evolution Exam III Questions With Complete
Solutions
A feature (features) of prebiotic conditions that were important
for the origin of life was (were)...
1. Organic molecules were concentrated by evaporation in small
pools and by freezing of water.
2. Organic molecules catalyzed chemical reactions that were
linked together in interdependent (autocatalytic) cycles.
3. Collections of organic molecules became trapped within lipid
membranes.
4. Both 1 and 2 are true.
5. Both 1 and 3 are true.
6. Both 2 and 3 are true.
7. All 1, 2, and 3 are true. Correct Answers 7. All 1, 2, and 3 are
true
After duplication both gene copies maintain the same function
but are expressed in different tissues. This is most consistent
with....
Subfunctionalization (EAC).
Whole genome duplication (WGD).
Dosage selection.
Neofunctionalization (MDN).
Small scale duplications (SSD).
Subfunctionalization (DDC).
Paleopolyploidy (ancestral polyploidy). Correct Answers
Subfunctionalization (DDC)
,After duplication both gene copies maintain the same function,
are expressed in the same tissue, and expression for both is
regulated by the same control region. This is most consistent
with ....
Subfunctionalization (EAC).
Dosage selection.
Neofunctionalization (MDN).
Subfunctionalization (DDC).
Small scale duplications (SSD).
Whole genome duplication (WGD).
Paleopolyploidy (ancestral polyploidy). Correct Answers
Dosage selection
After duplication one gene copy obtains a novel function (it did
not previously have this function). This is most consistent
with ....
Small scale duplications (SSD).
Neofunctionalization (MDN).
Dosage selection.
Subfunctionalization (EAC).
Subfunctionalization (DDC).
Paleopolyploidy (ancestral polyploidy).
Whole genome duplication (WGD). Correct Answers
Neofunctionalization (MDN)
After duplication, functionality of each copy is improved for a
different function - the original gene had partial functionality in
both roles. This is most consistent with ....

Ancestors of domestic dogs (wolves) typically do not live past
eight years. Dogs older than ten years are more susceptible to
diseases and have more medical issues than young dogs. This
can be explained by...
1. Selection for high fitness early in life in dog ancestors.
2. Antagonistic pleiotropy hypothesis of senescence.
3. Mutation accumulation hypothesis of senescence.
4. Both 1 and 2 are true.
5. Both 1 and 3 are true.
6. Both 2 and 3 are true.
7. All 1, 2, and 3 are true. Correct Answers 7. All 1, 2, and 3 are
true
Bateman's Principle states that:
1. Male reproductive success is generally limited by access to
mates.
2. Female reproductive success is generally limited by resources.
3. Males will have a higher variance in reproductive success
than females.
4. Both 1 and 2 are true.
