No. If mom has B and dad has B, the child can be B or O. The child can't be A or AB. Since, the rh factor (Rhesus factor) of the parents are just proteins attached to the red blood cells, they make no difference in determining blood type of the child. They do, however influence the rh factor (+ or -) of the child. B+ with B+ can be B+ , B, O+ or O. It can't be B-, O-, A+, A, A-, AB+, AB or AB-.

∙ 13y agoYes, positive blood can pass on a negative or positive Rhesus factor. If the two parents with Rh positive blood each also pass on Rh negative alleles, (if any of the child's grandparents were Rh- this is possible,) they can have a child with Rh negative blood. If there is no Rh- in the family (which would take an insurmountable amount of research for most couples to prove beyond doubt,) their children would be Rh+ like their parents and grandparents. Tracing the blood types of your child's grandparents and great-grandparents, (on both sides) to determine whether any of them passed on some Rh negative alleles to either of you would require a lot of cooperation on everyone's part. If Rh- can truly be proven NOT to be in either parent's family, then the answer is no.

∙ 10y agoOn 20 June, 2013 this question was answered in detail by Dr. P. Mariappan, Asst. Professor of zoology, Rajah Serfoji Govt. College, Thanjavur, Tamil Nadu on page 17 under the "Question Corner" of the Hindu Kochi City edition. According to him this is possible i.e., even when both parents are Rh positive, children born of them can be Rh negative!

∙ 11y agoYes, if both parents have the genotype B-O. From this, each parent can donate the "O" blood gene to the baby and the baby will be O-O. Also, at least one parent had to donate the Rh + gene to the baby.

∙ 14y agoIf both RH's are positive, there is not problem. A negative mother could have issues with a positive baby. OH is not a blood type. A, AB, B and O are the types. RH is a factor.

Can a baby be born with positive blood if both parents have negative blood?
No, it is not possible.
Can both o positive parents have a o negative baby?
Nope, the baby will be O positive as well.
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.
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.
Can a baby be born aids free if both parents have aids?
A baby can be born free from AIDS even if both parents have AIDS.
Can both parents be a b positive and have an o positive baby?
not if the mum is having an affair source ross.wikia.com
Can a B positive father and a a positive mother have a o positive baby?
yes... both parents may be heterozygous for their specifec genes...
Can o positive and a postivie make ab positive baby?
yes, if you both are ab pos you can have a o neg baby. it depends on what the grandparents on both sides have as well as the parents and which is "dominate"
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.
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 an a mother and ab- have an a- child?
Yes Yes, as both parents may be heterozygous. If that is the case, the baby may inherit the negative gene from both parents, and have no positive gene to express. In that case the baby will be Rh negative.
Can Two o positive parents have a ab positive baby?
No they cannot. If a parent is O, that means that their blood is IOIO, a child from this pairing would have inherited both O's from the parents.
