The child would most likely be ab plus but she/he could also be a or b.
No. The child would have A+
The only way that would be possible is if there was a mutation during the formation of one or both of the parents' gametes.
No if both parents are o+ they must produce o+ offspring
If both parents have genotype AO, it is possible to have a type O child, but this is very rare.
If both parents are O ,,,,,,,,,,,, all kids will be O ,, no possibility for A
If the parents are AO+ and BO-, they can create a O+ child: both parents contribute O and the AO+ parent contributes + (the child's genetic makeup would be OO+-). If the parents are AO+ and BB-, they could not create an O+ child as the BB- parent would contribute a B (possible combinations would be AB or BO in that case).
It could be possible, but only if both the parents are heterozygous.If the mother is AO and the father is BO - there is a 25% chance the child will be OO (O blood group).However, if either or both of the parents are homozygous (AA or BB) - then they cannot have an O child.
possibility not
A+ and A- A+ and O-
If both parents have genotype AO, then it is possible albeit rare for them to have a type O- child. If either parent is type AA, then the child will be type A.
If both parents are O- then the child will be O-.
Yes - it is possible. Firstly, if both parents have the blood type O, then the child must also have blood type O. Rh positive is dominant, so a person who is Rh + may be heterozygous (Rh+/Rh-). Both parents in this case would need to be heterozygous for the child to be Rh-.
