A biologist measures the allele frequencies of pea plants in a very controlled environment. The plants can either have a dominant tall allele (T) or a recessive short allele (t). Which of the following is a reason that this population is not at Hardy-Weinberg equilibrium?

A. The pea plants are mated at random.

B. Both alleles ensure equal survival.

C. One pea plant mutates to have a new allele.

D. Every pea plant reproduces exactly once.

The Hardy - Weinberg theory states that frequencis of alleles and genotypes will remain constant from generations to generationss without the evolutionary influences. From your choices, the three supports the Hardy - Weinberg equilibrim but letter C does not. There must be no new allele to be produced fro the mutation of the pea plant.
