If phenotype of father is blood group .O. and genotype of mother is heterozygous .A., what are the possible genotypes and phenotypes of the offspring ?

Explanation

To solve the question regarding the possible genotypes and phenotypes of the offspring from a father with blood group O and a mother with a heterozygous blood group A, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Genotype of the Father:**
- The father has a blood group O. The genotype for blood group O is represented as **ii** (homozygous recessive).

2. **Identify the Genotype of the Mother:**
