In four o’clock plants, there are three phenotypes for flower color, but only two alleles. The table shows both the expected and observed numbers of plants of each flower color in a population of 1,000.
Which statement best explains the results in the table?
A. The population is in equilibrium because the total number of plants expected and observed was about the same.
B. The population evolved because the frequency of the alleles and the genotypes changed.
C. The frequency of the alleles and genotypes in the population changed because of gene flow.
D. The observed frequency of the phenotypes is different from the expected frequency because some alleles mutated.
