Practice Questions

Question 1

Which of the following scenarios would most likely lead to a significant increase in the frequency of a deleterious recessive allele in a small, isolated human population?

Question 2

In a human population, if the frequency of the allele for a rare genetic disorder is $q = 0.005$, and the population is in Hardy-Weinberg equilibrium, what is the approximate frequency of individuals who are carriers for this disorder?

Question 3

A population of humans living on an isolated island exhibits a significantly higher incidence of a specific genetic disease compared to the mainland population from which they originated. This is most likely an example of:

Question 4

Which of the following best describes the concept of 'relative fitness' in population genetics?

Question 5

In a human population, if the frequency of the dominant allele 'A' is $p = 0.65$, and the population is in Hardy-Weinberg equilibrium, what is the expected frequency of individuals expressing the dominant phenotype?
