Analysis of Results

The population selected for this example has an equal frequency of dominant and recessive alleles in the initial population, but this is NOT what is meant by Hardy-Weinberg equilibrium! If this population is at equilibrium, the next generation will also have the same allelic frequency, and the next, and the next …

A class of 12 AP biology students gathered the following data:

Initial class frequencies:
AA = 3
Aa = 6
aa = 3

Final class frequencies:
AA = 2
Aa = 5
aa = 5

1. What are the initial p and q?

2. What are the final p and q?

3. Is the population in Hardy-Weinberg equilibrium? Explain the reason for your response.
