Quick quizzes to reinforce your learning

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 advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
