Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is allele frequency?

💡 Hint: Think about how often that allele appears in the population.

Question 2

Easy

What does the Hardy-Weinberg principle state?

💡 Hint: Consider conditions necessary for stability.

Interactive Quizzes

Engage in quick quizzes to reinforce what you've learned and check your comprehension.

Question 1

What is the Hardy-Weinberg principle used for?

  • To determine carrier frequencies
  • To model allele frequency change over time
  • To study genetic variation under equilibrium

💡 Hint: Think about what it models in a population.

Question 2

If a population is not in Hardy-Weinberg equilibrium, it is evolving. True or False?

  • True
  • False

💡 Hint: Consider what causes equilibrium to break down.

Challenge Problems

Push your limits with challenges.

Question 1

A population has 1,000 individuals with the following allele frequencies: 700 A, 300 a. Calculate the expected frequencies of genotypes and explain the implications for the population's evolution.

💡 Hint: Use the Hardy-Weinberg equations to find genotype frequencies.

Question 2

If a population's allele frequencies were found to deviate significantly from Hardy-Weinberg equilibrium, discuss the potential evolutionary mechanisms that might be at work.

💡 Hint: Consider both selective pressures and random environmental factors in your response.
