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 Δq?
◦ 5.00 × 10-9
◦ 9.45 × 10-7
◦ 9.50 × 10-7
◦ 9.55 × 10-7
◦ 5.26 × 10-3

Question 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?

GenotypeRelative Fitness
AA1.00
AD0.70
DD0.05

◦ 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.

Dogs have been used in studies to detect various cancers in human subjects. They have been trained to sniff breath samples from humans that were collected by having them breathe into special tubes. These people included 55 lung cancer patients, 31 breast cancer patients, and 83 cancer-free patients. The dogs detected 54 of the 55 lung cancer patients as having cancer, detected 28 of the 31 breast cancer patients, and gave only three false-positive results (detecting cancer in people who didn't have it).

In Eastern Europe and Russia, interferon is administered intranasally in varied doses for the common cold and influenza. It is claimed that this treatment can lower the risk of infection by as much as 60–70%.

Cutaneous mucormycosis is a rare fungal infection that has been fatal in at least 29% of cases, and in as many as 83% of cases, depending on the patient's health prior to infection. It has occurred often after natural disasters such as tornados, and early treatment is essential.
