Genetic drift refers to the change in the relative frequency of distinct genotypes in a small population, owing to the chance vanishing of specific genes as individuals do not reproduce or die. In the given case A, the population included 500 individuals of females and males in which the males compete heavily with the females for harems. In the given situation, the females give birth to one offspring in each season. In the case of B, the population includes just 250 individuals, and in this, the mating bond between the females and males goes through the mating season. In the given case, the females on an average give rise to 3 to 4 offsprings in a season.

The diagram below illustrates a quorum sensing pathway from Staphylococcus aureus. Please answer the following questions. 1. Autoinduction is part of the quorum sensing system. Which promoter (P2 or P3) is critical for autoinduction? 2)This staphylococcus aureus grows on human wounds, causing severe infections. You would like to start a clinical trial to treat these wound infections. Please describe: a) What molecule do you recommend for the trial. Why? b) Your trial requires that Staphylococcus aureus be isolated from the wound and submitted to genome sequencing before admittance. Why? What are you testing for? 3) If a mutation arises where the Promoter P3 is constitutively active, how would that influence sensitivity to AIP? Please explain your rationale. 4) This pathway is sensitive to bacterial cell density. Describe two separate mutation that would render the pathway active independent of cell density. Briefly explain your rationale. Mutation 1 Mutation 2
