Ab blood type is an example of?

Plato users, Codominance.


What blood type of Thomas A Edison?

He had blood type AB.


Which is better to view blood type AB or O?

If you add any antigen (A or B protein) to type O blood, it will coagulate (immunological reaction) and if you do the same to AB blood it won't, so you can figure out in both cases which blood type it is. If you add a colouring which connects to either A or B proteins, then that will show up coloured under a microscope. Type O lacks those types of proteins. Either one is easy to see, depending on the technique.


Type O is considered the theoretical universal?

Type O- is actually the theoretical universal donor; type O+ cannot donate to everyone. Blood has two main types of protein markers; an ABO group, and an Rh factor. There are also smaller, less important factors, but these two are what donors need to have a generally successful blood transfusion. ABO group proteins show up as A or B, therefore creating blood that has both (AB) and blood that has neither (O) as well as type A and type B. The Rh factor then either shows up or doesn't, so if someone doesn't have the factor, their blood type is -(negative), and if they do, then their blood is +(positive). If a person with O- got any other type of blood, then the blood would see the proteins on the blood as foreign invaders and attack it, whereas AB+ can receive from anyone without disease.


Why is AB blood referred to as universal?

Because it can be virtually accepted by anyone with little to no complications.
