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 would be a reason that this
population is not at Hardy-Weinberg equilibrium?
A. There are no mutations in the alleles for height.
B. Both alleles ensure equal survival.
C. The pea flowers are pollinated at random.
O D. One plant pollinates more flowers than the others.
