The child must have O as well.
No. The child would have A+
Only if it was adopted...the only options for that child's blood type would be A or O if the biological parents are both Type A.
The child would also have O-.
If both parents are genotype BB, the child can only be blood type B. The child's genotype would also be BB.
No, At least one parent would have to be an A (or an AB) for a child to have group A blood.
If both parents are B- they can only have children who are B- and O-. One would have to be positive in order to have a child with positive blood.
if both parents have positive o blood their child must have positive o blood
O- would be the only possible blood type for the child.
If both parents have A positive blood, their child would most likely also have A positive blood. This is because the child inherits one blood type allele from each parent, and A positive is dominant, so it is highly probable for the child to have the same blood type as the parents.
No. One of the parents would have to be type A or AB.
Yes. Both parents could be heterozygous, that is AO, and pass on the O to their child.
The child will be half-blood. A person can only be pure-blood if both parents are pure-blood, similarly, they can only be muggle-born is both parents are muggles. Otherwise they are half-blood.
