1. Genetics of Blood Types

2. Genotypes and Phenotypes Type A, Type B, Type AB and Type O blood are phenotypes. It is not always possible to tell the genotype of a person from their blood type. For example, a person with type A blood could have the genotype AA or AO A person with type B blood could have the genotype BB or BO

3. If a person has type AB blood they must have inherited an A allele from one parent and a B allele from the other. A person with type O blood must have the genotype of OO since the O allele is recessive to both the A allele and the B allele.

4. Rh factor Rh factor is inherited independently from the ABO blood factors. There are two alleles: Rh + and Rh- A person that is Rh+ might be Rh+/Rh+ or they might be Rh+/Rh- A person that is Rh- must be Rh-/Rh- Rh factor is inherited independently from the ABO blood factors. There are two alleles: Rh + and Rh- A person that is Rh+ might be Rh+/Rh+ or they might be Rh+/Rh- A person that is Rh- must be Rh-/Rh-

5. . Suppose a father of blood type B and a mother of blood type O have a child of type O. What are the chances that their next child will be blood type O? Type B? Type A? Type AB? Make a punnett square to show the possible outcomes.
