Can two parents with negative blood type have a baby with O positive blood type?

Yes parents who are both B blood group can have a child with O negative. This is because B blood group only requires one parent gene to be B to have B blood group - they may also have one O gene. People have two blood group genes, one from both parents. B gene is "dominant" as is A gene. O gene is "recessive". AB blood group means a person has one A gene and one B gene B blood group means a person has either one B gene and one O gene or two B genes A blood group means that a person has either one A gene and one O gene or two A genes O blood group means that a person has two O genes Rhesus positive or negative is similar - positive is dominant and therefore a person with one positive gene and one negative will be rhesus positive. A person who is rhesus negative has both negative genes, and received one negative gene from both parents, both who may be rhesus positive ( with one positive and one negative gene each). Importance of O negative blood - O negative blood group is called the "universal donor" because the blood is least likely to cause transfusion reactions so is safest to use in an emergency before blood groups can be identified and matched.
If both parents are A+ can a child be B+?

∙ 13y agoNo, this won't happen.
to have a positive child both parent should be positive.
or in some cases both are positive and they can give a negative child but with a low percentage reaches to 25% ( if both parent genotype are heterogeneous ).

∙ 12y agoit is possible but the child can be a positive
Wiki User
∙ 14y agoNo. Having O negative blood type, means that you don't have antigens- like type B or A. A child would be type A.

∙ 12y agoyes i has o negitive blood and she does to and we had one

∙ 15y agoYes, if they both have genes that are AO.

What are parents blood group with their first baby is of blood group o negative?
a positive
If a mother has a positive blood and father has o positive blood can the baby have ab negative blood?
it it possible if someone from either parents' family has had it or haves it because of genes
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.
Can two o positives make an o negative?
Yes this is true only if both parents are heterozygous positive. This means that the parents genotypes are +- for blood type. + blood type is dominant over - blood type, so this means that one can only have negative blood type if their parents are either heterozygous or homozygous recessive. A helpful tool to finding out the probability for this question would be to use a punnett square. If you used this method you would find out that two heterozygous positive blood type parents have a 25% chance of producing offspring with negative blood type.
What blood type can a child be if mother is A positive and father is o positive?
A or O Since both are positive, the baby can be either Rh positive or Negative hope that helped this is exactly like my parents but I have no idea what my blood type is... lol :)
Can parents with AB positive and A negative blood have a baby with 0 negative blood?
Yes
When Parents with b positive and o positive blood have baby with o negative blood group?
I'll wait for you to ask the question. Positive parents can have a negative baby as positive is dominant so they may both have one positive and one negative gene and the baby gets the two negative genes.
Can a baby be born with positive blood if both parents have negative blood?
No, it is not possible.
What are parents blood group with their first baby is of blood group o negative?
a positive
Can two parents with A positive blood have an Rh A negative baby?
not chance,but rarely can be.
What will two negative parents have positive or negative baby?
a negative times a negative is a positive so the answer is positive
How can a baby have b negative blood when both parents are b positive?
If both parents have Type B blood the only blood type the child can have is either B or O not looking at whether one of the parents is negative or not.
If a mother has a positive blood and father has o positive blood can the baby have ab negative blood?
it it possible if someone from either parents' family has had it or haves it because of genes
If you have A positive blood and your baby has O negative blood does that mean the father of your child would have to have negative blood?
no, he has at least one - but the other half could be + or - if baby is -- then both parents gave - meaning they both are one of these +- or --
Can a mother with A positive blood and father with O positive blood have a baby with A negative blood?
No. Rh negative is a recessive gene. Positive people do not carry it.
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.
Mother is o positive and father is o positive Does this mean baby will be o positive?
No. There's a small chance the baby will be O negative--if both parents have an Rh negative (recessive) allele, and the baby inherits this allele from both parents, the baby would be Rh negative. But if the baby inherits the Rh positive allele from either parent, the baby will be Rh positive.
