Gregor Mendel and Genetics Review At the end of this unit, students should be able to answer the following questions: What is the blending theory of inheritance? Why did Mendel question this theory? List the seven characteristics that Mendel investigated in pea plants. How did Mendel control pollination in pea plants? Describe in general terms Mendel’s first set of experiments. What was Mendel investigating with his second set of experiments? What was the outcome? State Mendel’s two laws. Assume you are investigating the inheritance of stem length in pea plants. You cross-pollinate a short-stemmed plant with a long-stemmed plant. All of the offspring have long stems. Then, you let the offspring self-pollinate. Describe the stem lengths you would expect to find in the second generation of offspring. If a purple-flowered, short-stemmed plant is crossed with a white-flowered, longstemmed plant, would all of the purpleflowered offspring also have short stems? Why or why not? If Darwin knew of Mendel’s work, how might it have influenced his theory of evolution? Do you think this would have affected how well Darwin’s work was accepted? Explain Mendel’s laws in genetic terms, that is, in terms of chromosomes, genes, and alleles. Explain the relationship between genotype and phenotype. How can one phenotype result from more than one genotype?
