Select the statements about Hardy-Weinberg equilibrium that are true.
I. Hardy-Weinberg equilibrium is often found in the wild.
II. The allele frequency of a population in Hardy-Weinberg equilibrium does not change. III. The Hardy-Weinberg equation predicts the evolutionary agent affecting a population.
A - I and III
B - I and II
C - I, II, and III
D - II and III
Answer: D - II and III
The Hardy-Weinberg equation can be used to determine whether or not the genetic makeup of a population is changing. The necessary criteria for a population are difficult to come by naturally.
