Is it possible to have a child of blood type O when the mother and father and her two brothers all have B blood type?

Yes,It is possible to have a children from two parents with B type blood. It could go either way the children could have B or O type blood.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
