The organism is exposed to an antibiotic that blocks the electron transport chain. Predict the relative growth rate under aerobic conditions (compared to the table) and explain how the cell would compensate. (2 points) Question 2 (20 min) A population of Wwxxyyzz is grown in a chemostat for 200 generations. Initially, all individuals have the same allele for a membrane transport protein. After 200 generations, two alleles (A and a) are present at frequencies: A = 0.3, a = 0.7. Defend your answer using biological definitions
