    About the Lecture

    The lecture Classic Mendelian Genetics by Georgina Cornwall, PhD is from the course Understanding Genetics. It contains the following chapters:

    • Classical Genetic Assumptions
    • Mendels Investigations of the Pea Plant
    • Monohybrid Crosses
    • Mendels Principles and Meiosis
    • Human Pedigrees
    • Dihybrid Crosses
    • The Principle of Independent Assortment

    Included Quiz Questions

    1. They have a short generation time
    2. They could both cross fertilize and self fertilize
    3. They are easy to grow
    4. There was no prior research on inheritance patterns in the garden pea.
    1. 3 dominant phenotype : 1 recessive phenotype
    2. 1 dominant phenotype : 2 heterozygous phenotype : 1 recessive phenotype
    1. An individual must carry two alleles (factors) for the same traits
    2. These alleles segregate from each other during gamete formation
    3. Gametes carry only one of these alleles (factors) - alleles are maintained discretely in gametes
    4. Homologous chromosomes align on the metaphase plate during meiosis
    1. False
    2. True
    1. 6 Tall Purple : 2 Tall white
    2. 9 Tall Purple : 3 Tall white : 3 short purple : 1 short white
    3. 4 Tall Purple : 7 Tall white : 3 short purple : 2 short white
    4. 6 Tall Purple : 2 Tall white : 2 short purple : 6 short white
    1. Factors segregate from each other indeopendently of any other factors.
    2. The principle of independent assortment
    3. Meiosis involves chromosomes separating from each other to form gametes
