Dr. Liu Feng
Children born to parents with blood type A and blood type B can have blood type A, B, O, or AB.
When a sperm or egg from a person with blood type A combines with a sperm or egg from another person with blood type A, the child will have blood type A.
When a sperm or egg from a person with blood type A combines with a sperm or egg from a person with blood type B, the child may have blood type AB.
Additionally, since individuals with blood type A or B can carry the recessive gene for blood type O, when an individual with blood type A (or B) mates with an individual with blood type B (or A) who also carries the O gene, the child's blood type may be A or B. If both parents contribute the O gene, the child will have blood type O.
