Question

A population of trout lives in a small lake. Some of the trout have a mutation that makes them more colorful. Describe two reasons this population is not at Hardy-Weinberg Equilibrium. (6 points)

Answer 1

This is not a Hardy-Weinberg population because,

1. Hardy-Weinberg equilibrium is attained only when the population is stable and doesn't have genetic drift, recombination, mutation etc.

2. In Hardy-Weinberg population gene frequency must be constant. In the given example gene frequency isn't constant.
