  2. Part 1: Vocabulary

  3. 1. The form of the gene that is “weaker” and can be hidden by another allele Dominant Recessive Genotype Phenotype

  4. 2. The form of the gene that is “stronger” and appears more often Dominant Recessive Genotype Phenotype

  5. 3. BB, Bb, and bb are examples Dominant Recessive Genotype Phenotype

  6. 4. Being tall or short are examples Dominant Recessive Genotype Phenotype

  7. The genes or instructions for a trait Dominant Recessive Genotype Phenotype

  8. 6. Is represented by letters Dominant Recessive Genotype Phenotype

  9. 7. The expression of a gene Dominant Recessive Genotype Phenotype

  10. 8. Could look like the recessive trait Homozygous Heterozygous

  11. 9. Would always look like the dominant trait Homozygous Heterozygous

  12. 10. bb is an example Homozygous Heterozygous

  13. 11. Bb is an example Homozygous Heterozygous

  14. 12. BB is an example Homozygous Heterozygous

  15. 13. BB would result in a _______ phenotype Dominant Recessive

  22. 19. Which is the correct way of filling in the punnett square?

  23. 20. Which is the correct way of filling in the punnett square?

  24. 21. Which is the correct way of filling in the punnett square?

  25. Part 3: Set Up

  26. How would you set up a punnett square for these parents? B = Black fur b= white fur • Draw a punnett square for a Mom who is heterozygous and a Dad who is homozygous recessive.

  27. How would you set up a punnett square for these parents? B = Black fur b= white fur • Draw a punnett square for a Mom who is homozygous dominant and a Dad who is homozygous recessive.

  28. How would you set up a punnett square for these parents? B = Black fur b= white fur 24. Draw a punnett square for a Mom who is homozygous recessive and a Dad who is homozygous for black fur.

  29. How would you set up a punnett square for these parents? B = Black fur b= white fur 25. Draw a punnett square for a Mom who is heterozygous and a Dad who has white fur.

  30. Part 4: Reading a Punnett Square

  31. B = Black fur b= white fur 26. What is the probability of a child with black fur?

  32. B = Black fur b= white fur 27. What is the probability of a child with white fur?

  33. B = Black fur b= white fur 28. What is the probability of a child with a homozygous genotype?

  34. B = Black fur b= white fur 29. What is the probability of a child with a heterozgous genotype?

  35. B = Black fur b= white fur 30. What is the probability of a child with a dominant phenotype?

  36. B = Black fur b= white fur 31. What is the probability of a child with a recessive phenotype?

  37. Part 5: Punnett Square Word Problems

  38. B = Black fur b= white fur 32. If mom is homozygous dominant and dad is homozygous recessive, what is the probability of their child having black fur?

  39. B = Black fur b= white fur 33. If mom is homozygous dominant and dad heterozygous, what is the probability of their child having white fur?

  40. B = Black fur b= white fur 34. If mom and dad are both heterozygous, what is the probability of their child having white fur?
