- The plant blue-eyed Mary grows on Vancouver Islandand on the lower mainland of British Columbia. Thepopulations are dimorphic for purple blotches on theleaves—some plants have blotches and others don’t. NearNanaimo, one plant in nature had blotched leaves. Thisplant, which had not yet flowered, was dug up and takento a laboratory, where it was allowed to self. Seeds werecollected and grown into progeny. One randomly selected (but typical) leaf from each of the progeny is shown inthe accompanying illustration.a. Formulate a concise genetic hypothesis to explainthese results. Explain all symbols and show all genotypicclasses (and the genotype of the original plant).Explain why the trees in the diagram looks the way they do.In bryophytes, eggs are fertilized in a chamber on the ________ and a zygote develops into a _______. a. sporophyte; gametophyte b. gametophyte; sporophyte c. sorus; cone
