Question
Chapter 22, Problem 3S
Summary Introduction
To explain:
The reason that why have differences in color evolved in sympatric populations of two species.
Concept introduction
Character displacement leads to divergence among similar species. It is common in allopatric population overlapping in sympatry show greater genetic divergence. Sympatry is exhibited by the species that are present in the same geographical area. Allopatry is exhibited when same species are separated by the geographical barriers.

(You may not need to use all four images. Stop counting when you reach 100 total cells.) After totaling the cells in each stage, calculate the percent of cells in each stage. (Divide total of stage by overall total of 100 and then multiply by 100 to obtain percentage.)

You submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Describe two characteristics that you would expect in seeds that are dispersed by the wind. Contrast this with what you would expect for seeds that are gathered, buried or eaten by animals, and explain why they are different.
