Competencies
- Define and describe the scope of the scientific field of genetics.
- Compare and contrast transmission genetics and molecular genetics.
- Explain the 19th-century “generative fluid” theory.
- Predict the outcome of reproductive crosses between red- and white-flowered plants using the generative fluid theory.
- Describe the long-term expected outcome of multiple rounds of reproduction using the generative fluid theory.
- Explain why that prediction invalidates the generative fluid theory.
- Describe the reproductive anatomy of a flower, and identify the main male and female structures of a flower.
- Describe how Gregor Mendel tested his pea plants to show that they were true-breeding before he began his experiments.
- Describe how Mendel performed cross-breeding experiments using two different varieties of parent plants, specifically on seed shape and seed color.
- Describe how Mendel performed his experiments on self-fertilization of pea plants.
- Describe in quantitative detail Mendel’s results using single traits, for all 3 generations we described in class (P, F1, and F2).
- Explain why these results can and cannot be explained by the generative fluid theory.
- Explain the scope of his results–how many traits in how many species did Mendel claim his observations applied to?
