When biologists study natural selection they are looking for changes in genotype or allele frequencies across generations in the real world. Based on the thinking you have just done about plant growth, density, and neighbors, which experimental treatment(s) is (are) most likely to give you information about relative fitness of the two morphs that would apply to nature? Why?
Understand the Problem
The question is asking for an analysis of experimental treatments related to plant growth, density, and neighbor interactions, specifically in the context of studying natural selection and relative fitness of two plant morphs. It aims to identify which treatments can effectively reveal how these morphs perform in natural conditions and the rationale behind selecting these treatments.
Answer
Treatment 3, involving inter-morph competition, is most suitable.
The experimental treatment most likely to give information about the relative fitness of the two morphs in nature is Treatment 3, as it involves inter-morph competition.
Answer for screen readers
The experimental treatment most likely to give information about the relative fitness of the two morphs in nature is Treatment 3, as it involves inter-morph competition.
More Information
Inter-morph competition can provide data on how different genetic morphs perform in the presence of one another, which can reflect their fitness in natural environments.
Tips
A common mistake is assuming that any treatment will reflect natural selection processes. The treatment must simulate natural conditions closely.
