absolutely. as long as one of the parents is positive, the child can be positive. and if one parent is A the other B, the child can be A, B, AB or O depending on the parents' other alleles. so the child can definitely be A or B positive, but also A negative, B negative, AB negative, AB positive, O positive or O negative.

∙ 11y agoNo. One parent would have to be Rh factor positive in order to have a child that was positive. If an Rh positive child is born to an Rh negative mother, the father must be Rh positive.

∙ 10y agoTwo O positive parents can only make a child with type O positive.
Each parent would carry a homozygous pair of O alleles:
OO
x OO

Can parents that are both a negative have an ab positive child?
No. If both parents are A negative the child can only be A negative or O negative. If the child is AB positive at least one parent must have type B or AB blood and at least one must be RH positive.
What are the possible blood types of a father if the offspring is A positive and the mother is O positive?
The first parent would be heterozygous for type A. The second parent would have to be heterozygous for type A, heterozygous for type B, or blood type O. The positive or negative is unable to be determined because positive is dominant so the first parent is positive then the baby will be positive with out a doubt so there is no way to find out the second parent's positive or negative.
What blood type will a baby have if one parent o positive and the other have o negative?
Either A- or B-. The AB parent will pass on either the A or the B. The other parent, of course, will pass on the O, which becomes recessive against either the A or B. Since both parents are negative, the child will also be negative by default.
What type of blood would you have if both your parents have RH blood type?
Rh is not a blood type by itself but is just one part of what makes up a blood type. There are two parts to blood typing: the ABO aspect and the Rh factor. One has blood type A, B, AB, or O, AND then is either Rh positive, or Rh negative. Hence why you hear blood types like A positive, O negative, etc. The positive/ negative is referring to the Rh factor. Rh positive is dominant, so one only needs one Rh positive parent so be Rh positive. Rh negative is recessive. If both parents are Rh negative, the child they have must be Rh negative as well. To know what blood type you could be, you need to know your parents' entire blood type.
Can two parents with A positive blood have a child with O negative blood type?
No.
Can a child have a negative blood types if the parents are both a positive?
Yes! Parents have two genes for pos/neg blood type, and only one of them needs to be positive for the parent to have positive blood type. Most positive-blooded people have one positive gene and one negative gene. If both positive parents pass on their negative gene, they can have a child with a negative blood type.
What blood group will a child be with parents who are B negative and O positive?
Answer Mostly with Parent's groupes.
Is it rare for an A positive parent and an O positive parent to have an A negative child?
It's rare, but can easily be explained by genetics. The A positive parent could be AA or AO for blood group, and the O positive parent would have to be OO for blood group. Both parents would have to be heterozygous for rh factor, Rh+ Rh- . So the A negative child would have to have inherited an A and O allele from the parents, and an Rh- allele from both parents. This gives the phenotype of A negative.
Will parents with a positive blood type have children with a positive blood type?
There is 50% that children will be of negative blood type if parents are heterozygous positive. 25% if one parent is homozygous and other heterozygous. 0% if both homozygous.
What type of blood will a child have if both parents are positive types?
The child will probably be positive, but they can be negative. Each parent has two genes for pos/neg blood type. The parent will have positive blood type if at least one of their genes is positive, but they could both also have negative genes to pass on to the child.
Can a parent with a positive and a parent with ab positive have a child with a negative blood?
rarely can be
Can parents that are both a negative have an ab positive child?
No. If both parents are A negative the child can only be A negative or O negative. If the child is AB positive at least one parent must have type B or AB blood and at least one must be RH positive.
Can negative blood type parent and positive blood type parent have an Rh negative blood type child?
yes, absolutely
Can a parent with O negative blood type and a parent with A positive blood type have a baby with O positive blood type?
Of course!
Can one parent have b positive blood and the other parent have a positive blood have an ab negative child together?
Yes, if the first parents' genotype is either BB+- or BO+-, and the second either AA+- or AO+-.
Can a parent with A positive and a parent with A negative have an O negative baby?
Yes. The parents' blood types are AO and AO so the baby will be OO. And since at least one parent is Rh+, the child will be Rh+.
Can an A negative parent and a A positive parent have a child who is AB negative blood type?
it can be rare only
