Practice Questions

Test your understanding with targeted questions related to the topic.

Question 1

Easy

What is a gene pool?

💡 Hint: Think about the total genetic diversity in a population.

Question 2

Easy

Define allele frequency.

💡 Hint: How common is a specific allele in the population?

Interactive Quizzes

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

Question 1

What is the Hardy-Weinberg Principle?

  • It states that allele frequencies remain constant under certain conditions.
  • It states that evolution does not occur in large populations.
  • It states that mutation is the only force of evolution.

💡 Hint: Recall the specific criteria for stability from our lesson.

Question 2

True or False: A small gene pool decreases a population's ability to adapt to environmental changes.

  • True
  • False

💡 Hint: Think about population vulnerability to diseases.

Challenge Problems

Push your limits with challenges.

Question 1

A population of beetles experiences a severe drought that favors individuals with a specific coloration. Describe the changes you would expect in allele frequencies due to this event.

💡 Hint: Consider how certain traits may impact survival and reproduction.

Question 2

Assume a population is initially in Hardy-Weinberg equilibrium but suddenly faces high migration from another population. Explain the potential impacts on allele frequencies.

💡 Hint: Think about how fresh genetic material can disrupt established patterns.
