Introduction to Biology
The following problems are on the inheritance of blood groups
in man. There are three alleles (A, B, and O) which interact as follows: AA and AO - blood group A
AB - blood group AB BB and BO - blood group B
OO - blood group O 1. List all of the possible blood groups that may occur in the
children of each of the following blood group crosses: AB x O A x AB B x B A x A A x O
2. a. Could a child of blood group O be born to parents both of whom are of
blood group A?
b. Could a child of blood group AB be born to these parents?
3. A mother of blood group A, one of whose parents was of blood group B, and
a father of blood group B have a child of blood group A. What other possible
blood groups can occur in their children?
4. Suppose a father of group A and a mother of group B have a child of group
O. What groups are possible in their subsequent children?
