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 advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
