Can two parents with b positive blood type have children?

Best Answers

Blood type has nothing to do with fertility, personality, what food you can eat or who you can marry. Blood type only matters in blood transfusions or when a Rhesus negative mother is pregnant with a Rhesus positive child. read more

Yes. People of any 2 blood types can have children. Their child has a 87.89% chance of having blood type B+, a 5.86% chance of having blood type B-, a 5.86% chance of having blood type O+, and a 0.39% chance of having blood type O-. read more

The A and B are dominant, and O is recessive. So allele A combined with allele O is type A. Similarly, BO is type B, AA is type A, BB is type B, OO is type O, and AB is type AB. If both parents have type A blood, then the alleles could be AA or AO, thus the allele A frequency is 75%, allele O frequency is 25% for both parents. read more
