Upon completion of this module, you will be able to:- Describe the scientific reasons for the success of Mendel’s experimental work (Course Outcome #1, 4)
- Describe the expected outcomes of monohybrid crosses involving dominant and recessive alleles (Course Outcome #1, 4)
- Apply the sum and product rules to calculate probabilities (Course Outcome #1)
- Explain the relationship between genotypes and phenotypes in dominant and recessive gene systems (Course Outcome #1, 4)
- Develop a Punnett square to calculate the expected proportions of genotypes and phenotypes in a monohybrid cross (Course Outcome #1, 4)
- Explain the purpose and methods of a test cross (Course Outcome #1, 4)
- Identify non-Mendelian inheritance patterns such as incomplete dominance, codominance, recessive lethals, multiple alleles, and sex linkage (Course Outcome #1, 4)
- Explain Mendel’s law of segregation and independent assortment in terms of genetics and the events of meiosis (Course Outcome #1, 4)
- Use the forked-line method and the probability rules to calculate the probability of genotypes and phenotypes from multiple gene crosses (Course Outcome #1, 4)
- Explain the effect of linkage and recombination on gamete genotypes (Course Outcome #1, 4)
- Explain the phenotypic outcomes of epistatic effects between genes (Course Outcome #1, 4)
To achieve these objectives:
- Read the Module 11 Introduction
- Read and view the materials in the Module 11 Pressbooks book, embedded below by section for the chapter titled Mendel's Experiments and Heredity
- Complete the assignment and discussion forum post and response.
This module's lab activity is included as well, to occur in the lab class. Slides are available to accompany the class lecture.
