Question

question 2 of 10
which of these is one of the conditions for hardy-weinberg equilibrium?
a. mutation cannot occur.
b. organisms must choose mates.
c. the population must be small.
d. only some organisms can reproduce.

Explanation:

The Hardy - Weinberg equilibrium has several conditions. One of them is that there should be no mutations. Mutations can introduce new alleles into a population, disrupting the equilibrium.

• Option B: In Hardy - Weinberg equilibrium, mating should be random, not that organisms must choose mates.
• Option C: The population must be large. Small populations are more likely to be affected by genetic drift, which violates the equilibrium.
• Option D: All organisms in the population should be able to reproduce (no selection pressure in terms of reproduction ability). If only some can reproduce, it implies selection, which is a violation of the Hardy - Weinberg conditions.

Answer:

A. Mutation cannot occur.
