  1. Mendel, Heredity and Punnett Squares

  2. Name one (human) trait that is determined by genes. • Name two alleles that determine that trait.

  3. Heterozygous is another name for…. • hybrid

  4. Homozygous is another name for…. • purebred

  5. The phenotype describes the ______ of an organism • Physical appearance

  6. The genotype describes the ______ of an organism • Genetic makeup

  7. What is this phase called in Mendel’s pea plant experiment? What were the genotypes of these father and mother plants?

  8. What phase was this in Mendel’s experiment? What were the genotypes of these plants?

  9. What phase was this in Mendel’s experiment? What percentage of the offspring were tall? What percentage were short?

  10. How many alleles do the offspring inherit from the “mother”, how many from the “father?” • 1 from the mother, 1 from the father

  11. Draw a punnett square for a crossing between a Tt and Tt plant: (T is tall, t is short)

  12. Draw a punnett square for a crossing between a Bb and bb mouse: (B is brown, t is white)

  13. Which allele is dominant?

  14. Which allele is recessive?

  15. What is the probability of getting a Yy pea pod?

  16. What is the probability of getting a yy pea pod?

  17. Draw two alleles that are homozygous…..

  18. Draw a pair of alleles that are heterozygous…..

  19. What is the probability of getting a heterozygous yellow pea pod?

  20. What is the probability of getting a homozygous green pea pod?

  21. Draw a punnett square for a crossing between a homozygous tall and homozygous short plant: (T is tall, t is short)

  22. Draw a punnett square for a crossing between a homozygous tall and heterozygous plant: (T is tall, t is short)

  23. What are the phenotypes of the parents?

  24. What are the genotypes of the parents?

  25. What are the genotypes of their offspring?
