Answer to Problem 30AYU

Totally 8 different kinds of blood are there.

Explanation of Solution

Given:

Human blood is classified as either $R{h}^{+}$ or $R{h}^{-}$. Blood is also classified by type: $A$, if it contains an $A$ antigen but not a $B$ antigen; $B$, if it contains a $B$ antigen but not an $A$ antigen; $AB$, if it contains both $A$ and $B$ antigens; and $O$, if it contains neither antigen.

From the given data, we draw the venn diagram as shown below.

$R{h}^{+}:O,A,B,AB$

$R{h}^{-}:O,A,B,AB$

Totally 8 different kinds of blood are there.
