    No. O is rarest. The chromosome pairs are made of A,B,O. A & B are Dominant, O is recessive. If I’ve done the math right, there’s 144 ways to combine the genes of parents giving a resulting distribution of
    A 33.3%
    B 33.3%
    AB 22.2%
    O 11.1%

    Because AA, AO, OA all result in type A… BB, BO, OB all result in type B… AB and BA both result in type AB… Only OO can produce type O blood.

    Edit: I assumed even distribution of alleles, which is incorrect as pointed out below.
