I'm O- and my sister is B+ Can this information alone tell you if we are full siblings or half siblings?
Can Siblings With The Same Parents Have Different Blood Types 1 O- And The Other A+?
What blood types would the parents have to be if one child is b+ and the other is a-?
What if Mother 0+, Father B+ - my sister is B+ me and my brother A+? Doesnt make sense to me :(
My dad has refused a d n a test.would I be able to have a test with my full sister ,to see if we have the same father
Blood type O- offspring can only come from an O- parent. Only one parent has to be O-. If the other parent is A+ then the offspring can have A+ or O+ blood. In this case, If one parent is A+ and the other is O- then the only blood types that they can produce is A+.A-, O+ or O-. If neither parent has O- blood then they can't possibly produce an O- child. If the siblings are A+ and O- then the parents MUST have A+.A-.O+ or O- blood.
Yes they actually can but it is a small chance.
Yes...blood group type is not herited...
Yes, siblings with the same parents could have O and AB blood types.
I am B - My brother is A positive do we have the same parents?
My blood group is 0- and my sister is A-. It has been hinted that we don't have the same father. Could we have the same father with these blood groups?
my brother is B+ and my sister is a+ but I am A-. Do we have the same parents?
They can yes BUT it all depends upon what the parents blood groups are and also whether they are pure for their groups. So sometimes the children have to be all the same but in other siblings there can be several differences.
One parent with A+, the other with A-, can they produce child with O blood group. The grandfather might be O or the grandmother. Can it be genetics if child has different blood group to the parents.
How can you get a child with one parent 0 posative and the other a neg and come up with an ab neg child
