The most likely blood type for the child is A positive - but A negative, O positive and O negative are also possible depending on the genotypes of the parents.
If both parents are heterozygous AO, then the child could have either A or O type blood. If either parent is homozygous, AA, then the child must have blood type A.
If the parent with positive blood is heterozygous, Dd (+-), then the child could have either positive or negative type blood. If they are homozygous, DD (++), then the child must have positive type blood.
If a baby is blood type B, the one parent must have a B. The possible combinations are:
One parent B (homozygous or heterozygous), other parent B (homozygous or heterozygous)
One parent B (homozygous or heterozygous), other parent A (heterozygous)
One parent B (homozygous or heterozygous), other parent AB
One parent B (homozygous or heterozygous), other parent O
One parent AB (homozygous or heterozygous), other parent O (homozygous or heterozygous)
The Rh factor must be either positive heterozygous or negative in each of the parents.
If one parent is AB- and another parent is B-, then the possible bloodtypes of their child is as follows:
AB-
BB-
B- [or BO-]
A- [or AO-]
There would be an equal chance of any one of these genotypes from occurring.
Both parents are rhesus-negative and have a genotype of BX (X being any of A, B and O), but nothing else can be determined.
can both be AB or must be different and neither can be type O
Blood type B or Blood type O
A or O -
The parents must have both blood type B or blood type 0 and B.
No. The parents must both have the type O allele in order for their child to be O.
if both parents have positive o blood their child must have positive o blood
Yes. The geneotype for both parents must be AO+- for the child to be OO--
No - this is not possible. The child must have one parent with an A allele in order to have type A blood. Neither of these parents have an A allele - so this is not possible.
It must have one of the true parents blood types.
The child must have O as well.
No - the child must recieve one allele from each parent. This means that because one parent is AB they must donate an A or a B to the child. In order for the child to be O both parents must have at least one O (AO, BO or OO).
Yes. The geneotype for both parents must be AO+- for the child to be OO--
the child takes the A gene from one parent and B from the other. And the both of parent are supposed to be AB blood type, or one A blood type and the other B.
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.
No. If two parents both have A blood then they are either AA or Ai. This means they can have a child with AA, Ai, or ii (O blood). To get AB there must be a B somewhere.
