6. You are conducting a genome wide scan of genetic diversity in humans and find that
there is a remarkably HIGH level of diversity (i.e. lots of polymorphisms from one
individual to the next) in a small region in the top arm of chromosome 12. What kind of
selection most likely generated this pattern? Provide a specific example of this type of
selection. [Your example does not need to come from humans.]
7. For each of the following sets of haploid genotype frequencies, calculate the linkage
disequilibrium coefficient (D) and state whether the AB genotype occurs with more, less,
or the same frequency as you would expect at random given the allele frequencies:
i. F(AB) = 0.3; F(Ab) = 0.2; F(aB) = 0.3; F(ab) = 0.2
ii. F(AB) = 0.4; F(Ab) = 0.1; F(aB) = 0.2; F(ab) = 0.3
iii. F(AB) = 0.2; F(Ab) = 0.3; F(aB) = 0.4; F(ab) = 0.1
8. You have discovered an interesting new leaf color variant in pea plants. You have some
wild-type plants with the typical green leaf color and some plants with...
