EVOLUTION TEST Chapters 16 & 17 – REVIEW SHEET
NAME THE SCIENTIST
Question
1. Scientific theory of evolution
2. Studied geological change over many years
3. Acquired characteristics in ones lifetime can be
passed on to offspring (cutting tails off of mice)
4. Human population growth would soon result in
limited resources
5. An organisms actions can alter structure of their
body
6. Individuals with the variations best suited to
their environments are the ones who survive
TERMINOLOGY REVIEW – CH 16
7. Part of the finch that Darwin noticed were
different on the different Galapagos islands
8. The fact that the finches still had similar beaks
led Darwin to the conclusion that the finches must
have shared this
9. What type of evolution are Darwin’s finches an
example of?
10. Ability of an organism to survive and reproduce
in its specific environment
11. Humans who select livestock with desirable
characteristics are practicing this
12. Where species and their ancestors lived – can
be closely related but different, or distantly related
but similar
13. Structures that are no longer used in an
organism – provide information about common
ancestors (ex/hip bones in dolphins, appendix)
14. Structures that are similar in design but
different in functions (ex/bird wing and human arm)
15. Structures that have same function but
different design – show convergent evolution
(ex/bird wing & insect wing)
16. How does DNA provide evidence for evolution
Answer
Darwin
Lyell
Lamarck
Malthus
Lamarck
Darwin
Beaks – were suited to their food
sources
Common ancestor
Speciation by adaptive radiation
Fitness
Artificial selection
biogeography
Vestigial structures
Homologous structures
Analogous structures
All organisms on earth share a nearly
universal genetic code (same 4 letters A,
T, C, G)
TERMINOLOGY REVIEW – CH 17
17. All of the alleles of a population of species
18. If evolution is occurring, what happens to the
allele frequencies in the gene pool
19. List the two Hardy-Weinberg equations
Gene pool
They change
p + q = 1 (allele frequencies)
p2 + 2pq +q2 = 1 (genotype frequencies)
19.b List the 5 conditions for Hardy-Weinberg
equilibrium to exist for naturally occurring
populations
20. What are the three sources of genetic
variation?
21. What does the number of phenotypes for a
given trait depend upon?
22. What shape does a polygenic trait graph display
(number of individuals vs phenotypes)
23. Which produces more phenotypes, a single trait
gene or a polygenic trait?
24. What kind of selection results when those at
either end of bell curve have better fitness than
those in middle?
25. What kind of selection results when those at
center of curve are better fit for their environment?
26. What kind of selection results when those at
one end of curve have higher fitness than those at
other end?
27. The phenomenon that occurs when an allele
becomes more or less common b/c of chance
28. What kinds of populations tend to have more
genetic drift?
29. What kind of genetic drift occurs when a few
individuals colonize a new area?
30. Separation of a population by a river
31. In order for speciation to occur, this must
happen between two populations
32. Members of a population that can interbreed
and produce fertile offspring defines this
1. large population size
2. no mutations
3. no immigration or emigration
4. no natural selection
5. random mating
 Mutation
 genetic recombination in sexual
reproduction
 lateral gene transfer
The number of genes (alleles) that are
controlling that trait
Bell curve
Polygenic
Disruptive
Stabilizing
Directional
Genetic Drift
Small populations
Founder effect
Geographic isolation
Reproductive isolation
species
33. Three ways #31 can occur
34. Which of #33 would occur if one deer species
mates in October, while another mates in
November?
HARDY WEINBERG PRACTICE:
Behavioral Isolation
Geographical Isolation
Temporal Isolation
Temporal Isolation
In a population of 1,000 students, 910 of the individuals have free earlobes, which is dominant to attached
earlobes. Assuming that this is a stable Hardy-Weinberg population, what is the frequency of the dominant
allele (F) and the recessive allele (f)?
If 910 have free, then 90 students have attached. Attached = 90/1,000 = .09 = q2
If q2= .09
Then q=.3 and p=.7 (p+q = 1)
How many students in this population are homozygous dominant, heterozygous, and homozygous recessive?
Homozygous dominant = p2 = (.7)2 = .49 X 1,000 students = 490
Heterozygous = 2pq = 2 (.7)(.3) = .42 X 1,000 students = 420
Homozygous recessive = q2 = (.3)2 = .09 X 1,000 students = 90
