(i) `l^(A)i xx l^(A)i` , (ii) `l^(B)i xx l^(A)xxl^(A)`
(iii) `ii xx l^(A)i` , (iv) `l^(B)l^(B) xx l^(B)i`

What is the phenotype of the following (a) l^(A) i (b) ii

Prove that: L = I omega

if the genotypes determining the blood groups of a couple are l^(A)L^(B)" and "L^(A)L^(B) , then the probability of their first child having type O blood is
