Question 1
In a theoretical population where
f (
A1) = 0.95 and
f (
A2) = 0.05, µ = 1 × 10
-6, and
v = 1 × 10
-7, what is Δ
q?
◦ 5.00 × 10
-9◦ 9.45 × 10
-7◦ 9.50 × 10
-7◦ 9.55 × 10
-7◦ 5.26 × 10
-3Question 2
In an insect species, survival in agricultural fields regularly sprayed with insecticide is determined by the genotype for a detoxification enzyme encoded by a gene with two alleles,
A and
D. Which of the following statements is consistent with the data?
| Genotype | Relative Fitness |
| AA | 1.00 |
| AD | 0.70 |
| DD | 0.05 |
◦ This will likely lead to the frequency of the
A allele being eliminated (
f=0.0) and the
D allele being fixed (
f=1.0).
◦ Eventually, natural selection should lead to a balanced polymorphism.
◦ The
D allele frequency will change faster as it gets less frequent.
◦ Both the
A and
D alleles should reach stable equilibrium frequencies that are maintained in a steady state.
◦ Directional selection will increase the frequency of the
A allele at a pace determined by the intensity of natural selection.
