Recognize that evolutionary change is the result of natural selection.- Describe how the concepts of evolution and natural selection are related.
Understand how natural selection works.- Explain why genetic diversity is essential for natural selection to occur.
- Describe how individuals produced by sexual reproduction can have fitness different from that of their parents.
- Explain how mutation and migration affect the genetic diversity of a population.
- Explain why excess reproduction is important to the concept of natural selection.
- List and describe three circumstances that can prevent a specific allele from being expressed in the phenotype of an organism.
- Describe common misunderstandings about the nature of natural selection.
- Explain how survival, reproductive success, and mate selection can alter gene frequency from one generation to the next.
Understand that evolution is the process of changing gene frequencies.- Describe the conditions that can lead to genetic drift.
- Explain how natural selection can change the nature of a species.
- Provide examples that indicate that evolution is occurring.
Recognize the conditions under which the Hardy-Weinberg concept applies.- List the five conditions necessary to prevent gene frequency changes according to the Hardy-Weinberg concept.
- Explain why Hardy-Weinberg conditions rarely occur.
