If the mother is AB+ blood group and the father is O+ blood group, what will the childrens blood group be?
If Parents Had Blood Group (o) And (b) Will The Child Have Blood (ab) Group?
No, well, not unless there was a serious mutation when the offspring was formed as an embryo. Because neither parent has an A allele, and O is entirely recessive. To get offspring with blood type O, that person has to inherit a type O allele from each of their parents. So the person with type O blood can only pass on type O alleles to their chidlren -- not A.
To get type B, the person must have received two type B alleles from their parents, or one type B allele, and one type O (type B is dominant). So again, no A in sight to pass on.
AB blood type occurs when one of the parents had a type A allele, and one parent had a type B allele. People only have two alleles to choose from when having offspring, and their offspring only get one from each parent.
If one of the parents had a type AB blood and the other parent had type O, there is a chance that their child could have type AB if there was crossover from the maternal alleles; this would be very rare, though.
To get type B, the person must have received two type B alleles from their parents, or one type B allele, and one type O (type B is dominant). So again, no A in sight to pass on.

If a parent has O blood type, his or her offspring cannot be AB blood type The offspring of these two parents can only be O or B blood type.
[There are three genes for blood group. They are all written I (capital I), and then a superscript letter of whichever group it codes for. For example, for the O gene, it would be written as I, and then what looks like a degrees sign after it. As this is bothersome to type, I will say 'A gene' etc. The A gene and the B gene are 'codominant'. That is to say, neither dominates over the other. In other words, If both are present in the child, the child will have AB blood. Both A and B genes dominate over the O gene, so if a child has A and O genes or B and O genes, it would be of A blood or B blood respectively.]
Let's say the father is the O and the mother is the B.
As the O gene is recessive two of them are needed to produce an O blood group phenotype (a phenotype is a characteristic).
As the A and B genes are co-dominant, to produce a B blood group phenotype, two B genes are needed.
As there is not an A gene in either of the parents, and at least one is necessary to produce an AB child, the child will not be of the AB blood group.

If the father has type o blood can his off spring have type a blood
