Parents must be blood type A or O. Any other blood type will not result in a sole A type child. It might result in several other combinations though, which are not relevant to this question.
Yes. Blood types do not make parents incompatible.
The likelihood of a child's blood type being determined by the blood types of their parents is high, as blood type inheritance follows specific patterns based on the parents' blood types.
Yes, parents with O and A blood types can have a child with A- blood type. The child would inherit one A allele from the parent with A blood type and one negative Rh factor from the parent with O blood type.
No they cannot. They can only have a child with type A or type O blood.
A+ and A- A+ and O-
Yes, we all get our blood groups from our parents or grandparents.
No, a child's blood type is determined by the combination of the parents' blood types. The child's blood type will always be a result of the parents' genetic information.
Yes, it is possible for two parents, one with AB+ blood type and the other with O+ blood type, to have a child with O+ blood type. When two parents with different blood types have a child, the child's blood type can be a combination of the parents' blood types through genetic inheritance.
No. They could have an A- child, but not A+.
It must have one of the true parents blood types.
They could, but they don't need to. Both of your parents must have at least one O allele, meaning neither can have type AB blood. They must be either BO, AO or OO to produce a child with type O blood.
No, because A & B are dominants.
