Yes D = Rh+, d = Rh- If both parents are heterozygous (D d), then the baby can get d from each; therefore, resulting in Rh- Also can get D from 1 parent & d from other parent resulting in Rh+ Or can get D from each parent, resulting in Rh+ As for B & AB, The parent which is type B has genotype of BO or BB both of which would result in B type. AB parent has only 1 option for genotype, AB The baby gets 1 gene from each parent, so possibilities for baby are: AB, B (genotype BO or BB; B is dominant), A (genotype AO; A is dominant) This baby could be type A+ A- B+ B- AB+ or AB-

Father AB positive and mother B positive can child be A negative?
Yes, it is possible for parents who are AB positive and B positive to have a child who is A negative. This is because a child can inherit one A and one Rh negative gene from the parents, resulting in blood type A negative.
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 parents who are B negative and O positive have a AB positive child?
No, it is not possible for parents with blood types B negative and O positive to have a child with AB positive blood type. The AB blood type requires an A allele from one parent and a B allele from the other, which is not possible in this case.
Can two parents with O positive blood have a child with AB negative blood?
No. O is recessive. The parents would have to have A and B phenotypes in order for their child to have AB- blood.
Can parents with B negative and AB positive have a child with O negative?
No, parents with B negative and AB positive blood types cannot have a child with O negative blood type. The O blood type is inherited from both parents who must pass on the O allele to the child. Since neither parent in this case carries the O allele, they cannot have a child with O negative blood type.
Can parents with both negative blood parent a positive child?
Yes, parents with both negative blood types can have a child with a positive blood type. This can happen if both parents are heterozygous for the Rh factor, meaning they carry one positive and one negative allele, and they pass on the positive allele to their child.
Can parents having blood type AB positive and O negative have a child with O positive blood type?
yes
Can a father with AB negative have a child?
Of course, you got your blood group from one of your parents or one of your grandparents.
Can a A Negative Father and an AB Positive mother have an A Negative child?
The child will be A or B or AB, Rh+ or Rh- . So yes, the child can be A-.
Can parents who are AB negative and O negative have a B positive child?
Yes, if the AB parent contributes a B allele, and the O parent contributes an O allele, then the child will be BO, and will have type B blood.
Can an o positive and ab positive have an a negative child?
No, an O-group parent cannot have an AB-group child at all.
Can two parents with b positive make o positive?
Yes. The child will be either A positive or B positive or even AB positive. If the grandparents have a negative (A negative, B negative), there is a slight chance that the child will have a negative. A type O is out of the question. The fact that there are two positive parents means that there is no risk to the mother of Rh negative disorders.
