It's possible.very very much possible. 100% sure about this.

As long as we B+ve about the story ... anything will do!

I think it is possible. My parents have different blood groups but both are positives. I share my father's group while my siblings share my mother's. However, I know a couple that has different groups and one is a positive while the other is a negative. They have recently got a baby. So both Arnav and Anjali can have different blood groups. It's just dangerous for a pregnant mother to bear a child when her blood group is a opp sign since the fetus might be harmed. My grade 11 biology teacher told me that the antibodies in her body will fight against threats and it might feel that the child is a threat. Thus, the chance of survival for a baby is difficult but some people still give birth to healthy babies.

Yup they can b.Actually i gave my specialization paper today.It can happen.I can explain u if u want to.Actually ABO blood group is inherited differently and + or - is inherited differently.

same thing in my mind...lol

even I was confused with it..

Yes, possible 😊...

If one sib gets the AB antigen from parents & the other gets none (i.e. 0, zero).. but one of their parents has to be negative..

oh then the combination i wrote is correct right? n thanks😃
