45. Lesson 5Punnet Square Practice
46. Practice Problem 1 - Part 1Earlobes have two forms.Unattached earlobes are dominant (E). Attached earlobes are recessive (e). The father is heterozygous. Question: What is his genotype?Answer: His genotype is Ee because he is heterozygous.FatherEe46
47. MothereeEeMotherPractice Problem 1 - Part 2Question: If the mother has attached earlobes, what is her genotype?Answer: Her genotype must be ee because attached earlobes are recessive.47Father
48. FatherMothereEeEEeeeeeeePractice Problem 1 - Part 3So the father is heterozygous (Ee)The mother is homozygous dominant (ee).Question: What are the chances that their offspring will have attached earlobes?Answer: There is a 50% chance because there are two boxes with the ee genotype.48
49. FatherMotherDDDDddDDddddPractice Problem 2Dimples are a dominant trait (D)Not having dimples is the recessive trait (d).A mother is homozygous dominant (DD)The father is homozygous recessive (dd).Question: What are the chances they have children with dimples.Answer: 100% will have dimples because all possible children carry at least one dominant allele.49
50. Practice Problem 3Freckles (F) are a dominant trait.Not having freckles is a recessive trait (f). Question: If mother is a heterozygous and a father is a homozygous recessive, what are the chances that their offspring will have freckles?Answer: There is a 50% chance that their offspring will have freckles because the dominant allele appears half the time.MotherFFffffFfffff50
