  1. Blood Type • Trait controlled by multiple alleles • Alleles are A, B, and O A, B over O 1. Which alleles are dominant? O 2. Which alleles are recessive? 3. Which alleles are codominant? A and B

  2. Blood Type Problems • Bob has A type blood and Emily has B blood. Their child has O blood. • Identify the genotypes of all 3 people. • Calculate the probability that Bob and Emily will have a AB child. • Raul has A blood. Raul and his wife Isabel have a child with AB blood. • Identify the possible genotypes of all three

  3. Blood Type Problems • Leo has B blood type. His wife Sherri has AB blood. Half of their children have AB blood, and half of their children have B blood. • What is Leo’s genotype? 4.
