In a large natural population of Mimulus guttatus, one leaf was sampled from each of a large number of plants. The leaves were crushed and subjected to gel electrophoresis. The gel was then stained for a specific enzyme, X. Six different banding patterns were observed, as shown in the accompanying diagram.

 Which one of the following conclusions is most appropriate based on the above observations?

A) There are three alleles of one locus and that the individuals with two bands are heterozygotes.

B) There are two alleles of one locus and that the individuals with two bands are heterozygotes

C) Population is present as hardy-Weinberg equilibrium

D) Population is not present as hardy-Weinberg equilibrium
