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+?
What else can I help you with?
What are parents blood group with their first baby is of blood group o negative?
If the first baby has blood group O negative, it means that both parents must have passed on an O gene and a negative Rh factor gene to the baby. Therefore, the parents could have blood groups A, B, AB, or O with negative Rh factor.
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 a O negative parent and an RH O negative parent make a positive baby?
No, if both parents are O negative (meaning they do not have the Rh antigen), they cannot have a Rh positive baby. RH positive blood type requires the presence of the Rh antigen when processing blood types.
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.
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.
Can two parents with A positive blood have an Rh A negative baby?
not chance,but rarely can be.
What blood type can a baby be if the father and mother are both type B positive?
A baby can be any blood type that is possible through the combination of the parents' genetic material. In this case, the baby could be blood type B positive like the parents, or it could be blood type O positive if both parents are carriers of the O blood type gene.
What are parents blood group with their first baby is of blood group o negative?
If the first baby has blood group O negative, it means that both parents must have passed on an O gene and a negative Rh factor gene to the baby. Therefore, the parents could have blood groups A, B, AB, or O with negative Rh factor.
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 O negative parent and an RH O negative parent make a positive baby?
No, if both parents are O negative (meaning they do not have the Rh antigen), they cannot have a Rh positive baby. RH positive blood type requires the presence of the Rh antigen when processing blood types.
Can a mother with A positive blood and father with O positive blood have a baby with A negative blood?
Yes, it is possible for a mother with A positive blood and a father with O positive blood to have a baby with A negative blood. The baby would inherit one A allele from the mother and one O allele from the father, resulting in A negative blood type.
