Unformatted text preview: e 2. Consider the following graph showing the relationship between the frequency of allele A1
(p) and the change in frequency of that allele due to selection (Δp). Answer the following
questions based on the graph. You can ignore the effects of mutation, migration, and drift
in answering these questions.
a. Would you expect selection to push the A1 allele towards fixation or maintain a
stable polymorphism in the population?
b. Do you think that A1 is dominant or recessive, or is this a case of heterozygote
0.04 delta p 0.03
0 0.5 p 1 3. True or False. It is more difficult to purge (i.e., eliminate) a deleterious recessive allele
from a population with high levels of inbreeding than from a population with frequent
4. Consider a population that is initially in Hardy-Weinberg equilibrium. There is a locus
with two alleles (A and a). The frequency of the “A” allele is p = 0.8. [Show your
calculations. You do not need to explain your answers for this que...
