3. Blood type is inherited. If both parents carry genes for the O and A blood types (i. e., Phenotype Type A, or Genotype AO), a Punnett Square such as the one below can help
determine the probability of a particular blood type for each child. O is a recessive gene,
meaning that the only way to have Type O blood is to have the genotype 00. What is the
probability of the following?

i. Child has Type O blood? (1 point)
ii. Child has Type A blood (any genotype)? (1 point)
iii. Child has Type A blood and cannot have children with Type O blood? (1
point)
iv. Child has Type A blood and can have children with Type O blood? (1
point)
b. This couple had 4 children. this exercise, we are considering the number of
children with Type O blood.
i. What is success in this exercise? What is the probability of success, p? (2
points)
ii. What kind of probability distribution is this exercise? Explain your
reasoning. (5 points)
