question 5 of 10
what idea did hardy and weinberg disprove?

a. allele frequency is stable between generations.

b. there are seven conditions for equilibrium.

c. the gene pool for a population frequently changes.

d. dominant alleles become more common in each generation.

Explanation:

The Hardy - Weinberg principle shows that in a non - evolving population, allele frequencies remain stable. They disproved the idea that dominant alleles necessarily become more common each generation. Option A is what the Hardy - Weinberg principle supports (allele frequency can be stable). Option B: The Hardy - Weinberg equilibrium has 5 conditions, not 7. Option C: The Hardy - Weinberg principle shows that the gene pool can be stable, not that it frequently changes. Option D was a common misconception that Hardy and Weinberg disproved, as their principle shows that dominant alleles don't have to increase in frequency each generation.

Answer:

D. Dominant alleles become more common in each generation.
