I. Standards
Topics, Concepts and Standards
Activity/Lab
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:
1. Students know why natural selection acts on the phenotype rather
than the genotype of an organism.
2. Students know why alleles that are lethal in a homozygous
individual may be carried in a heterozygote and thus maintained in a
gene pool.
3. Students know new mutations are constantly being generated in a
gene pool.
4. Students know variation within a species increases the likelihood
that at least some members of a species will survive under changed
environmental conditions.
5. Student know the conditions for Hardy-Weinberg equilibrium in a
population and why these conditions are not likely to appear in
nature.
6. Student know how to solve the Hardy-Weinberg equation to
predict the frequency of genotypes in a population, given the
frequency of phenotypes.
Evolution is the result of genetic changes that occur in constantly
changing environments. As a basis for understanding this concept:
7. Students know how natural selection determines the differential
survival of groups of organisms.
8. Students know a great diversity of species increases the chance that
at least some organisms survive major changes in the environment.
9. Students know the effects of genetic drift on the diversity of
organisms in a population.
10. Students know reproductive or geographic isolation affects speciation.
11. Students know how to analyze fossil evidence with regard to
biological diversity, episodic speciation, and mass extinction.
II. Objectives: Answer on a separate piece of paper. Answers do not need to be in complete sentences, however your
answers must be thorough.
YOU MUST BE ABLE TO:
1. Describe the differences between natural selection and artificial selection.
2. Explain how Darwin’s finches and tortoises show speciation.
3. Explain what caused the speciation of salamanders in California.
4. Explain how reproductive isolation, ecological competition, changes in a gene pool, and geographic isolation can
produce a new species.
5. Explain how geological evidence contributed to Darwin’s theory of natural selection.
6. Explain how inherited variation and artificial selection are related.
7. Explain the four pieces of evidence Darwin used to support the theory of evolution.
8. Explain the difference between a single gene trait and a polygenic trait.
9. Explain how natural selection can affect gene frequencies.
10. Explain the Hardy Weinberg Equilibrium.
11. Identify the 5 conditions required to maintain genetic equilibrium.
12. Describe 2 processes that lead to inherited variation.
14. Explain the 3 types of selective pressures on polygenic traits.
15. Interpret graphs of natural selection on polygenic traits.
16. Explain how fossils are evidence for evolution, and describe where fossils are found.
III. Vocabulary: Define vocab words and know how to apply them.
