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 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 a baby have B negative blood if the mother is B positive and the father is A negative?
Either. We know the mother is homozygous recessive rh- rh- for rh factor, so she can only pass on an rh negative allele to a child. However, if the father is heterozygous rh+ rh- for rh factor, he could pass on one of those two alleles to a child. If he passes on the rh+ (dominant) allele, the baby would be rh positive. If he passes on the rh- allele, the baby would be rh negative.
Can a 0 positive mother and a A negative father have a A Rh's negative child?
Yes. The mother would have to have a heterozygous Rh genotype, so that she could pass on an Rh negative allele to her offspring.
Can we pass the Rh factor to our offspring?
It is a fact that parents pass on their Rh factor to their children. When it is the rare negative factor this can cause issues with pregnacy.It would be wise to do further investigation if you are planning a pregnancy.
If the parents are Rh positive could they produce an Rh negative child or just Rh positive offspring?
We are looking for the possible Rh blood types of a baby.Parental information:Mother Rh pos -- can be (++) or (+-) = contributes (+) or (-) geneFather Rh pos -- can be (++) or (+-) = contributes (+) or (-) geneBaby receives one gene from each parent: Baby is Rh (++) = Rh posBaby is Rh (+-) = Rh posBaby is Rh (--) = Rh negTherefore, depending on the exact genetics of the parents, the baby may be Rh positive or negative.
Why do rh positive parents have an rh negative baby?
Each person carries two bits of rh imformation, called alleles, and each can be positive or negative. A person is rh+ if they have at least one positive allele. Only if both their alleles are negative are they considered as rh-. When two parents have a baby, they each pass one allele on. So if both parent has one positive and one negative allele, and both passed on their negative allele to their baby, then the baby would be rh negative. The chances of two rh positive parents having a rh negative baby are about 18%.
Can a baby be born with positive blood if both parents are negative?
No. If both parents are Rh negative, they are homozygous recessive for the Rh factor and can only pass on recessive alleles to their children, and a positive Rh factor is a dominant trait.
If both parents are rhesus positive can they have a negative baby?
Yes, if both parents each have the dominant positive AND recessive negative genes, they have a 1 in 4 chance of having a child with rh-neg blood. Both mother and father would have to pass the recessive gene to the offspring.
Can an AB positive blood type and an A positive blood type have a child with A negative blood type?
Yes. If both parents are heterozygous (rh+ rh-) for rh factor, they could each pass on an rh- allele to the child and it will be rh negative. As for blood group, as long as the child inherits either two A alleles (AA) or one A and one O allele, it will have the A blood group.
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 -
A woman who is o positive have a baby with an o negative man?
If a woman with O positive blood has a baby with a man who has O negative blood, the child will inherit one O allele from each parent, resulting in an O blood type. The Rh factor of the child could be either positive or negative, depending on the combination of the Rh factors inherited. Since the mother is Rh positive, she can pass on either a positive or negative Rh factor, while the father can only pass on a negative Rh factor. Therefore, the baby could be either O positive or O negative.
