BIO 110 Final Exam Study Guide
Latest Updates 2024/2025

The study of immature forms of an organism ANS✔✔ embryology



Preserved remains, impression, or trace of any once-living thing from a past
geological age ANS✔✔ fossil



Specific characteristics or behaviors influence mate selection ANS✔✔
nonrandom mating



Prevents fertilization - issues with mating times, courtship behaviors, or
physical displays ANS✔✔ prezygotic mechanisms



Prevents viable offspring - infertility of a hybrid ANS✔✔ postzygotic
mechanisms



Matings occur without consideration of physical or behavioral characteristics
ANS✔✔ random mating



Which of the following is not a basic cause of evolution?

a. genetic mutations

b. gene flow

c. inheritance of acquired characteristics

d. genetic drift

e. natural selection ANS✔✔ c. inheritance of acquired characteristics

,Situation A: A toad population's size is drastically reduced by a flood,
creating a group of toads that are less genetically diverse.

Situation B: Male deer with larger antlers are more attractive to females and
so they are more likely to successfully mate and pass on their genes to the
next generation than males with smaller antlers.

Situation C: Two populations of caribou live relatively close to each other.
Occasionally a caribou from one herd will mate with a member of the other
herd.

Which situation describes the bottleneck effect?

a. Situation C

b. Situation A

c. Situation B ANS✔✔ b. Situation A



If two adjacent populations of the same species show gene flow, then the
two populations will

a. develop into different species.

b. become more similar in their gene pools.

c. adapt to different conditions and become separate.

d. become isolate from each other. ANS✔✔ b. become more similar in their
gene pools.



Which is the correct order of steps regarding allopatric speciation?

a. reproductive isolation --> two species --> reproductive isolation --> one
species

b. reproductive isolation --> one species --> reproductive isolation --> two
species

c. geographic isolation --> one species --> reproductive isolation --> two
species

,d. one species --> geographic isolation --> reproductive isolation --> two
species ANS✔✔ d. one species --> geographic isolation --> reproductive
isolation --> two species



Almost all living organisms have the same triplet DNA code and many similar
proteins. This is evidence for evolution based on

a. comparative anatomy.

b. comparative embryology.

c. biogeography.

d. comparative biochemistry.

e. the fossil record. ANS✔✔ d. comparative biochemistry.



A variety of genotypes and phenotypes in a population is useful to that
organism because it

a. means that the gene pool is constant and unchanging.

b. makes gene flow in and out of a population unlikely.

c. makes life more interesting.

d. may allow the species to survive if the environment changes.

e. makes genetic drift an unlikely occurrence. ANS✔✔ d. may allow the
species to survive if the environment changes.



A biologist is studying the speciation of organisms without geographical
barriers. Based on this information you would conclude that he/she is
studying

a. ecological speciation.

b. microevolution.

c. allopatric speciation.

, d. hybrid speciation.

e. sympatric speciation. ANS✔✔ e. sympatric speciation.



A condition where the number of chromosomes is more than two sets
(diploid) is referred to as

a. gametoploidy.

b. haploploidy.

c. polyploidy.

d. zygoploidy.

e. symploidy. ANS✔✔ c. polyploidy.



The Hawaiian Islands are inhabited by several different species of
honeycreepers. These species of birds evolved from a single species based
upon different food sources and occupying different niches. This is an
example of

a. adaptive radiation

b. eutrophication

c. sympatric speciation

d. microevolution

e. mass extinction ANS✔✔ a. adaptive radiation



Which of the following is NOT an example of sympatric speciation?

a. Over millions of years a canyon becomes too deep to be crossed by
squirrel populations on either side of the canyon. Reproductive isolation
causes the development of two different squirrel species.

b. As the cichlid population grew in Lake Victoria, competition for food also
grew. New food sources were discovered at different depths. Changes in
