What is the blood type which is considered 'royal?

Anybody can possess the Rh O-Negative, alias the 'Royal Blood', as it is not restricted to royalties.The royal blood is a specific blood group. It is the Rh O-Negative. It is a very rare group. So rare that when it was discovered to be running in the veins of a royal family and their descendants, it was named the 'Royal Blood'. Anybody can possess the Rh O-Negative, alias the 'Royal Blood', as it is not restricted to royalties.The Rh O-Negative is a Universal Donor, i.e. someone possessing this blood group can donate his/her blood to anyone, irrespective of their blood groups. This is a sort of blessing, as you can save anybody. The big problem with it is that the Rh O-Negative recipient can only receive blood of Rh O-Neg type which is, as I said before, very rare.
