10.Divergent Evolution
A. Evolution in which a group from a population
becomes a new species
* A group “diverges” from the norm to become
new species
i.e.: humans- Modern Humans evolved into our
own species when we diverged from
neanderthals.

population
d. None of the above
13. Stabilizing Selection
a. Favors average individuals in a population

14. Gene Pool
a. Random assortment of alleles
b. Alleles of individuals
c. all alleles of a population
d. a place where genes can relax and
get a tan
14. Gene Pool
c. all alleles of a population
15. Allelic Frequency
a. Radio wave frequency of alleles
b. percentage of a certain allele in
a population
c. the change in alleles over time
d. alien frequency used for
communication
15. Allelic Frequency
b. percentage of a certain allele in a
population
Hint- Frequency: how often something
occurs.
- So basically allelic frequency helps
determine how often an allele occurs
in a population
16. Genetic Drift
a. What happens if you let alleles into
a race car
b. known as genetic equilibrium
c. total amount of alleles in a
population
D. change of allelic frequencies due to
chance events
16. Genetic Drift
D. change of allelic frequencies due
to chance events
Hint- Genetic Drift disrupts genetic
equilibrium
17. Genetic Equilibrium
A. Frequency of alleles remains the
same
B. Frequency of alleles rapidly changes
C. Frequency of alleles due to chance
events
D. None of the above
17. Genetic Equilibrium
A. Frequency of alleles remains the
same
Hint- Equilibrium- balanced, does not
change
- Therefore genetic equilibrium is where
the allele frequencies are balanced and
do not change over time
18. Gradualism
A. Idea that species evolve really fast
B. Idea that species evolve quickly with long
periods of genetic equilibrium in between
C. idea that species evolve slowly through
gradual change of adaptations
D. theory used by high school students
when homework is assigned.
18. Gradualism
C. idea that species evolve through gradual
change of adaptations
Hint- Gradual: means slowly
i.e. I pour the water gradually into the cup.
Gradualism- species evolve slowly
(Although I think answer D works as well!)
19. Punctuated Equilibrium
A. Idea that species evolve really fast
B. Idea that species evolve quickly with long
periods of genetic equilibrium in between
C. idea that species evolve slowly through
gradual change of adaptations
D. theory used by high school students
when homework is assigned.
19. Punctuated Equilibrium
B. Idea that species evolve quickly with long
periods of genetic equilibrium in between
Analogy- Imagine that genetic equilibrium is
a balloon, just minding its own business,
nothing changing. And then all of a sudden
you puncture it with a needle, suddenly
everything changes.
20. Polyploid
A. Any species with multiple sets of
chromosomes
B. Any species with a normal set of
chromosomes
C. Species with heterozygous alleles
D. I have no idea
20. Polyploid
A. Any species with
multiple sets of
chromosomes
- resulting from errors
in mitosis and meisis
21. Reproductive Isolation
A. Interbreeding populations
B. interbreeding populations that no
longer produce offspring due to
differences in their genetics
C. interbreeding populations that no
longer produce offspring due to an
environmental barrier
D. None of the above
21. Reproductive Isolation
B. interbreeding populations that
no longer produce offspring due to
differences in their genetics
i.e. horse and mules
22. Speciation
A. Process in which alleles are
separated
B. time it takes for species to evolve
C. the formation of new species from
an original population
D. I have no clue
22. Speciation
C. the formation of new species
from an original population
23. Geographic Isolation
A. Interbreeding populations
B. interbreeding populations that no
longer produce offspring due to
differences in their genetics
C. interbreeding populations that no
longer produce offspring due to an
environmental barrier
D. None of the above
23. Geographic Isolation
C. interbreeding populations that no
longer produce offspring due to an
environmental barrier
i.e. Rivers, mountains, islands can
physically separate species that causes
them to evolve differently.
