Answer each with a brief outline or paragraph. Use course vocabulary and
include specific examples and definitions (as needed; not in the math
questions).
1.
What are the processes of microevolution? How do they relate to each
other and to Darwin’s original theory?
2.
You have sampled a population in which you know that the percentage of
the homozygous recessive genotype (aa) is 36%. Using that 36%, calculate
the following:
A.
B.
C.
D.
The frequency of the "aa" genotype.
The frequency of the "a" allele.
The frequency of the "A" allele.
The frequencies of the genotypes "AA" and "Aa."
3.
There are 100 students in a class. Ninety-six did well in the course whereas
four blew it totally and received a grade of F. Sorry. In the highly unlikely
event that these traits are genetic rather than environmental, if these traits
involve dominant and recessive alleles, and if the four (4%) represent the
frequency of the homozygous recessive condition, please calculate the
following:
a. The frequency of the recessive allele.
b. The frequency of the dominant allele.
c. The frequency of heterozygous individuals.
4.
Which processes of microevolution were important for the Carolina Five?
Give examples.
5.
What are some of the conservation issues affecting lemurs? What are some
of the possible solutions?
6.
If a population is in Hardy-Weinberg equilibrium, what do we know about
the processes of microevolution at work in that population? Why?
7.
Distinguish sexual selection from assortative mating and provide real-world
examples of each.
