3. Mendel found the following statistics
in his experiments with pea plants: 522 white peas, 1584 green peas.
Assuming that all the offspring were from the same parents:
a) which allele is dominant?
b) what was the genotype of the parents? Draw a Punnet square to diagram this cross.
4. What ratio of children would have brown
eyes is you crossed 2 people who were heterozygous for brown eyes?
5. Why are half of all children male?
Explain in relation to mitosis.
6. A woman has type A blood. Her
husband has type B blood. They have a child who has type O blood.
Could the husband be the father? Use a Punnet square (or squares)
in your explanation (not as your explanation).
7. Examine the pedigree:
-Label each individual with his/her genotype. Use “E” for the dominant allele and “e” for the recessive.
-What is the mode of inheritance of the trait exhibited by those “darken” individuals?
