11.2 Natural Selection in Populations
Populations, not individuals, evolve.
|
| A | B |
|---|
| normal distribution | distribution in a population in which allele frequency is highest near the mean range value and decreases progressively toward each extreme end |
| microevolution | observable change in the allele frequencies of a population over a few generations |
| directional selection | pathway of natural selection in which one uncommon phenotype is selected over a more common phenotype |
| stabilizing selection | pathway of natural selection in which intermediate phenotypes are selected over phenotypes at both extremes |
| disruptive selection | pathway of natural selection in which tow opposite, but equally common, phenotypes are selected over the most common phenotype |
