Yes. Both parents could be heterozygous, that is AO, and pass on the O to their child.
If both parents have a positive blood type, the chances of their child inheriting a positive blood type are 100.
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.
No. If both parents are type O, the child will also be type O.
If both parents have O blood type, the chances of their child also having O blood type is 100.
The child's blood type is determined by his or her parents' blood types. If both parents have type A, the child can have either type A or O. If both parents have type B, the child can have either type B or O. If one parent has type A and the other parent has type B, the child can have type A, B, AB, or O, but he/she is most likely to have type AB. If both parents have type O, the child will have type O.
Yes, if both parents have the genotype AO, then the child can have the O from both parents, phenotype O
Yes
The parents must have both blood type B or blood type 0 and B.
If both parents are type O blood they will only have type O children
If they both have type A blood, they cannot have a child type B.
Yes this could happen if the geno-type of both parents is heterozygous, what i mean by that is to have this symbol for both parents : IAi X IAi so to have a child with type O, the possibility for that is 25%
It is not possible for two parents with blood types AB and B to have a child with O blood type. A child's blood type is determined by the combination of their parents' genes, and O blood type requires both parents to have at least one O gene.
