Answer 2

Explanation:

To have a child with O blood group, both paretns should have atleast one copy of i allele. This means parents with A and B blood group are heterozygous and have genotype IAi and IBi respectively. Parental genotypes IAi and IBi give progeny with 1 IAIB: 1IBi: 1 IAi : 1 ii genotypic ratio.
