The plant blue-eyed Mary grows on Vancouver Island and on the lower mainland of British
Columbia. The populations are dimorphic for purple blotches on the leaves --- some plants have
blotches, and others don't. Near Nanaimo, one plant in nature had blotched leaves. This plant
which had not yet flowered, was dug up and taken to a laboratory, where it was allowed to self.
Seeds were collected and grown into progeny. One randomly selected (but typical) leaf from
each of the progeny is shown in the figure below.
a. Formulate a genetic hypothesis to explain these results. Explain all symbols and show all
genotypic classes, including the genotype of the original plant.
b. Test the hypothesis you have formulated using the Χ2 statistic. Show all of your work for full credit
