Mendel’s Principle of Independent Assortment

Competencies

  1. State Mendel’s exact observations for the 2-trait cross in the F1 and F2 generations for seed shape and color.
  2. State Mendel’s quantitative observations for the 2-trait cross in the F1 and F2 generations.
  3. Explain these results using Mendel’s principles of segregation and independent assortment.
  4. Determine genotypes and phenotypes for Mendelian traits given phenotypes and genotypes in a pedigree (family diagram).
  5. Solve all possible 2-trait, Mendelian crosses using Punnett squares.
  6. Predict the outcome of Mendel’s test of the Principle of Independent Assortment using a test cross.
  7. State Mendel’s observed results of the test cross and interpret the results. What hypothesis was he testing, and did the results support, contradict or say nothing about that hypothesis?
  8. Describe Walter Sutton’s discoveries.
  9. Explain how Sutton’s discoveries relate to Mendel’s principles.
