does a B negative type people and a ab negative people produce a o positive baby? from R.T.

Not possible. Type o blood is recessive, so genotype must be OO, the B negative person may carry an O recessive gene....but the AB person carries only A and B. There will be no children with O type blood from this couple.

No, it is not possible. We carry two pairs of chromosomes to determine the blood type. In this case, we have an AB ( type A and type B, both dominant) and a B ( who can be BB or BO, these are the two combinations ) The baby could be B or A or AB, these are the 3 possible combinations, but not O. About the Rh, if you are negative, it means you are carrying two negative RH genes, since it is a recessive trait, so the baby would be necessarily negative.
I hope this helps
Cheers

No, it is not possible. The possibilities from B neg and AB neg parents are A neg, B neg, AB neg. There is also a possibility of being A pos, B pos or AB pos, if the expression of the Rh (the pos/neg part) antigen in the parents is very weak, they may have been given the wrong blood group status. It is the O group which is not possible. Of course, there is a possibility that the A or B group antigen is very weak also, and is assigned Group O, but this is rare.

a 'B" parent and an 'AB' parent can only produce A, B, and AB children, not O. Also, 2 'negative' parents cannot make a 'positive' baby.

No, as O is recessive. You need two, OO, to express O blood type.

0 positive is usually found in native american indians.
A is usually found in those of White European descent
B is usually found on the African continient.
Indians produce other indians, Europeans usually produce other Europeans. But in America where the slaves were forced to have sex with the slave owners AB is common.
But they rarely produce an Indian.

i don't think so...but maybe if the grandparents are o postive...(but it's dangerous to the baby and to the mother if they have different blood types.)

no, can only be 'A', 'B' or 'AB'
