  1. Evolution Science Content Standards

  2. 7. The frequency of an allele in a gene pool of a population depends on many factors and may be stable or unstable over time. As a basis for understanding this concept • Students know why natural selection acts on the phenotype rather than the genotype of an ororganism.

  3. 7. The frequency of an allele in a gene pool of a population depends on many factors and may be stable or unstable over time. As a basis for understanding this concept b. Students know why alleles that are lethal in a monozygous individual may be carried in a heterozygote and thus maintained in a gene pool.

  4. 7. The frequency of an allele in a gene pool of a population depends on many factors and may be stable or unstable over time. As a basis for understanding this concept c. Students know new mutations are constantly being gererated in a gene pool.

  5. 7. The frequency of an allele in a gene pool of a population depends on many factors and may be stable or unstable over time. As a basis for understanding this concept d. Students know variation within a species increases the likelihood that at least some members of a species will survive under changed environmental conditions.

  6. 8. Evolution is the result of genetic changes that occur in constantly changing environments. As a basis for understanding this concept • Students know how natural selection determines the differential survival of groups of organisms.

  7. 8. Evolution is the result of genetic changes that occur in constantly changing environments. As a basis for understanding this concept b. Students know a great diversity of species increases the chance that at least some organisms survive major changes in the environment.

  8. 8. Evolution is the result of genetic changes that occur in constantly changing environments. As a basis for understanding this concept d. Students know geographic or reproductive isolation affects speciation.

  9. 8. Evolution is the result of genetic changes that occur in constantly changing environments. As a basis for understanding this concept e. Students know how to analyze fossil evidence with regard to biological diversity, episodic speciation, and mass extinction.
