Answer: The baby cannot have type O blood.
Some extra relevant information:
When it comes to determining the blood type of a child, understanding the inheritance patterns is crucial. In this case, we have a man with AB blood and a woman with type B blood. Let’s explore the possible outcomes and debunk the false statement.
The ABO blood typing system categorizes blood into four types: A, B, AB, and O. Each blood type is determined by the presence or absence of antigens (A and B) on the surface of red blood cells.
In this scenario, the man has AB blood type, which means he carries both A and B antigens. On the other hand, the woman has type B blood, indicating she has only B antigens.
When these two individuals have a baby, there are three possible blood types that the child may inherit: A, B, or AB. The child cannot have type O blood since both parents lack the O antigen.
Now, let’s evaluate the statements:
1. The child could have AB blood: This statement is true. If the child inherits the A antigen from the father and the B antigen from the mother, their blood type will be AB, just like the father.
2. The child could have B blood: This statement is true. If the child inherits the B antigen from both parents, their blood type will be B, similar to the mother.
3. The child could have type O blood: This statement is false. As mentioned earlier, both parents lack the O antigen necessary for the child to have type O blood. Therefore, the child cannot have type O blood.
To summarize, the false statement is that the child could have type O blood when a man with AB blood and a woman with type B blood have a baby. The child can only have blood types A, B, or AB.
