Categorize
Individuals at one end of the curve have higher fitness
Average individuals have higher fitness
Individuals at both ends of a curve have higher fitness
Example: Antiobiotic resistance
Example: Both dark- and light-colored mice do better in their respective environments.
Maintains multiple alleles in population
e.g. sickle-cell trait in malaria regions
Selection favors one extreme phenotype over others
Can lead to rapid evolutionary changes in a population
Selection favors intermediate phenotypes
Example: Human birth weight where very low and very high weights have higher mortality
Reduces variation in a trait
Species with average traits are at a disadvantage
Can lead to speciation as populations diverge
Promotes genetic diversity within a population
Can lead to heterozygote advantage
Organize these examples into the correct category of natural selection.

Multiple Choice
In the past, individuals in a population of mice had a wide variety of coat colours. After many generations, the mice either have white coats where they live in the snow or dark cats where they live on the soil, but medium colours are absent. If the number of mice with each coat colour was graphed which example would it look like?

Multiple Choice
Starlings produce an average of five eggs. If there are more than five the parents cannot adequately feed the young. Fewer than five and predators may destroy them. As a result, five eggs becomes the most common number.
