Can a child have o positive blood type from an o positive mom and an ab positive dad?

your blood type doesnt really depend on your parents. Yes he can
this is not exactly correct. Your blood type DOES depend on your parents. But if the father has type B, the mother can have type A, B, or O and the child can still have type O blood. The only way this would not be possible is if the mother had AB blood.

∙ 15y agoNo. O is a recessive blood type, and a person with type O blood has two copies of the gene for type O. A is dominant, so a person with A type blood could either have two A copies or one A and one O. (If the father were AB instead of A, then that would be a different story.) A child with type B blood has to have either two B copies or one B and one O. The necessary B gene can't come from either of those parents, so it's impossible.

∙ 13y agoNo this is impossible, because for the O+ to come there should be two identical chromosomes (ii) , and the AB+ type has (IAIB), so even if one of the parents has an (i) in his/her blood type, there is another (i) should be come from the other parent, but his/her blood type is AB+ so there is no other (i).
it all about genetics :)

How can a child's blood type be A positive if mom is O positive and dad is AB negative?
because the dad blood was stronger and one positive and one negative make a positive
If both parents are A positive can a child be B positive or negative?
Maybe. A child will have either the mother's blood type or the father's blood type. If the father is B+ and the mother is A- then it is possible that the children have the same father. So it all depends on both parent's blood type.Source: I am a 2nd year nursing student, and we had a long discussion about this subject last semester.
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.
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.
What are the possible blood types of a father being that the mother is b positive and the child is ab positive?
You dad can either be O, AB, A,or B and he can be positive or negative.
What blood type would a child have if dad is A positive and mom is O positive?
o
Can a child have o positive blood type from an o positive mom and an o positive dad?
Yes.
Can a child have b positive blood type from an o positive mom and b positive dad?
yes they can
Can a child have b positive blood type from an o positive mom and an ab positive dad?
Sure.
How can a child's blood type be b positive if mom is b positive and dad is a positive?
You could have several children with different blood types. you get your blood type from either parents or even grand parents.
Can a child have A positive blood type from an AB positive mom and an O positive dad?
Yes. If you cross parents with AB and O, you can have children with either A or B blood types.
Can a child have o positive blood from an ab positive dad and an a positive mom?
no
Mom has a positive blood type dad has b negativeblood type can it produce a child with o positive blood type?
Since O blood is recessive and B is dominant, this scenario would be possible
How can a child's blood type be A positive if mom is O positive and dad is AB negative?
because the dad blood was stronger and one positive and one negative make a positive
Can a child have ab positive blood type from a A positive mom and o positive dad?
Not possible. If the mother is A+, there are two possibilities, AA or AO, and if the father is O+, there is only one possibility, OO. therefore, the only possibilities of the child's blood type will be either A [AO] or O [OO].
How can a child's blood type be b positive blood if mom is o positive mom and dad is o positive?
It is a little difficult to say but there is a question of parenthood here. The child cannot be type B if both parents are seen to be type O. The father must have a blood type of AB or B. Please see... http://www.dna-bioscience.co.uk/did_you_know_abo.shtml
Can a mom a blood type and a dad with b blood type have a child with o blood type?
yes
