Father and mother ( B and O) the father alleles here are heterozygous (IBi)
IBi ... ii
children are :
IBi , IBi , ii , ii
so 50% of children may be type B
& 50% of children may be type O
but if the father B type is homozygous ( IBIB)
100% of children will be type B ,,, (IBi)
if father is (Rh+Rh+) and mother (Rh-Rh-)
all kids will be Positive.
but if father (Rh+Rh-) and mother (Rh-Rh-)
50% of children will be +
50% of children will be -.

What if mom and dad both 0 positive - and child b negative?
Then the father of the child is someone else with B Negative blood group.
Mother with AB- blood group and father with O plus blood groupwhat group will be the child?
My dad is AB- and my mom is O+. I was told that my blood type could be any with this combination of parents. As it turns out I am B+.
Is it true that to have a child with O blood type both parents have to be O type?
No, this is not true. The child has to inherit two type O genes, however. Blood type is inherited as a co-dominant factor. For instance: Mom is A+, but her blood type genes are A and O. Because of the codominant nature of blood types inheritance, her blood is type A. Dad is O-. He has two type O genes. If, during fertilization, an ovum from the mother with type O gene combines with one of Dad's spermatozoa, the child will be type O. If an ovum with type A gene is fertilized, however, the resultant child will have type A blood. Same goes for mom who is A and dad who is B, so long as their genes are A/O and B/O, they can still have a type O child. If mom is A/O and dad is B/B, however, there is no chance the child will have type O. The child could have type B (B/O pairing) or AB, however.
Can a woman with B blood and a man with AB blood have a child with O BLOOD?
No - this is not possible. The child must inherit one allele from each parent. This means that at least one parent must have a B allele in order for the child to have B-type blood. The only possibilities with B- X AB are B, A or AB.
What would be the blood type of the child if the mother is B plus and the father is A plus?
ab+ a+ b+
If mom has A plus and dad had B can the Child have B plus?
The child would be AB plus, so yes.
Can an a positive mom and b positive dad have an a positive child?
no
Can a b positive mom and dad have an o positive child?
yes
If mother is B- and father B plus can child be AB?
If my mother is b- and my dad is b+ could there be a child ab- please
Can a type A- mom and B plus dad have A plus baby girl?
yes they may have a plus baby girl
Barack Obama's blood type?
Barack is type AB, so there are several possibilities: Mom A, Dad B Mom B, Dad A Mom AB, Dad A Mom AB, Dad B Mom A, Dad AB Mom B, Dad AB Mom AB, Dad AB
Can a child have b positive blood type from an o positive mom and b positive dad?
yes they can
If mom has a or o blood type and dad has o and the child had B plus plus does this mean one of the parents are NOT biological?
Yes! The genotypes of the parents can only be "OO" (means two O genes) so both of them cannot give a "B" gene to the child
What if mom and dad both 0 positive - and child b negative?
Then the father of the child is someone else with B Negative blood group.
Can a B-type mom and b-type dad bear a o-type child?
yes due to genotype.
Can a mom a blood type and a dad with b blood type have a child with o blood type?
yes
Can a child have b positive blood type from an o positive mom and an ab positive dad?
Sure.
