if you receive B blood allele from both parents then the blood type is BB, which is B positive. B negative would be B0 where one parent donates B allele and the other 0. Its all the great wonders of genetics. You see, parents pass on traits from themselves to their children. In the case of blood type, each parent has 2 alleles, but they can only donate 1. So the child's blood type is then reflective of both parents. So if one parent was B0 and the other was AB. The first parent can donate B or 0, while the second can donate A or B. The child can have any combination of them but must receive one from each parent. So AB, BB, B0, and A0 are the possible combinations for these parents. Crazy stuff
