no. because if the child's blood type is B, one of the parent must have type B or type AB but non of them has it. so it is impossible for the father to have typeA.
No
no
Absolutely. A child will either have its mother's blood type or its father's blood type. If the mother's blood type is NOT O, then someone else is the father.
Yes, the father with blood type B+ could be the biological father of a child with blood type A+. A child can inherit a different blood type from their parents due to genetic inheritance involving multiple alleles for the ABO blood group system.
NO
The child could be A+ or O+.
Could be B or could be O.
Yes! You could produce a child with either A or B blood.
They could be anything depending on the parental genotype.
Blood types are received from the mother and father, so the child can be the same type as the mother if the father's type allows it.
Yes, if both the father and mother have the genotype of AO, then they would both show up as phenotype A and they could have a child with type O blood. As O is recessive, the type A would be dominant and therefore show up as the blood type. The mother could contribute the positive Rh factor leading to type O+ in the child.
I'm not sure how negative or positive is determined, but a B mother and O father can have a B child.
