Summary Introduction
To analyze:
How natural selection “weeds-out” alleles that cause sickness and death early in life.
Introduction:
Various diseases result from mutations in genes, and these can remain in the population if they are passed onto the next generation.

how would you write an hypothesis and prediction from the given data?
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).
