For ABO blood groups in the humans, the A and B genes are codminant. Both A and B are dominant over O
a. Identify the possible blood types in the children of a man with blood type O and a woman with blood type AB.
My work: The possible blood types that the children could have are A,A-,A+,B,B-,B+,O,O-,O+.
b. Could a woman with the blood type AB ever produce a child with blood type AB? Could she ever have a child with blood type O?
My work: I believe a woman with the blood type AB could produce a child with the blood type AB because she could breed with a man that could have the same blood type as her thus increasing the chances of the child having the same blood type. Yes she could have a child with the blood type O as the gene for blood type O would be recessive as the genes for both blood type A and blood type B are dominant.
