Can parents with both negative blood parent a positive child?
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.
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 b positive and O positive have a b negative child?
Yes, that's True. for Rh- to come, both parents should be Heterozygous.
Can a child born with rh negative blood type be the offspring of an o positive father?
It depends on the genotype of the Rh+ parent. If that person is heterozygous, then yes there is a 50% chance of an Rh- baby.Father's Group (negative)Mother's Group (positive heterozygous)Rh +Rh -Rh -Rh +, Rh -Rh -, Rh -Rh -Rh +, Rh -Rh - Rh -http://www.bloodbook.com/inherited.htmlIf the positive parent is homozygous, the baby will be positive:Father's Group (negative)Mother's Group (positive homozygous)Rh +Rh +Rh -Rh +, Rh -Rh +, Rh -Rh -Rh +, Rh -Rh + Rh -
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 a A positive blood type mother give birth to Rh negative daughter?
Can a child with RH neg blood come from parents that are A positive and A negative
Can o positive and a positive parents have o negative child?
Yes. Since the Rh factor is recessive if both parents have a copy of the gene they can have an Rh negative child.
Can 2 Rh parents have a Rh- child?
No, it can't happen. if one of the parents or both are +, the child will be Positive. I don't know if 2 negatives can have a positive. But i do know that if one of the parents is positive and the other is negative, you can have a either a positive or negative child. (I have twins, one is negative and the other is positive.)
Can an a positive parent and an O negative parent have an A negative child?
No. If both parents are Rh+, they can only pass on Rh+.
Can an A positive parent and an O positive parent have an A negative child?
No. If both parents are Rh+, they can only pass on Rh+.
Can a positive parents have o negative child?
No, it can't happen. if one of the parents or both are +, the child will be Positive. I don't know if 2 negatives can have a positive. But i do know that if one of the parents is positive and the other is negative, you can have a either a positive or negative child. (I have twins, one is negative and the other is positive.)
Can A positive parents have A negative child?
Yes. A negative Rh factor is recessive. Everyone has 2 copies of this gene (one from mom, one from dad.) Since positive is dominant and negative is recessive, if you have one of each (heterozygous), you will have a positive blood Rh, but sitll carry the gene for negative Rh. If this is the case for both parents, then the child has a 25% chance of being Rh negative.
Can parents with both negative blood parent a positive child?
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.
If both parents are A positive can a child have negative blood?
Yes. If both parents have the recessive gene for Rh negative, a child of theirs could have Rh negative blood. I have two daughters who are Aneg, and both of us are A+.
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.
Is it possible for an O positive father and an a positive mother to produce an a negative child?
First of all, you should know that for a person to be positive there is two possible geno-typesRh+Rh+ or Rh+Rh-so to have a negative child both parents should be Rh+Rh---> and so Yes , this is possible but with possibility reach to 25%.
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.
