Question
There are four blood types: A, B, AB, and O. However, there are three alleles that control blood type: IA, IB, and i. Alleles IA and IB are codominant, and the allele “i” is recessive.
What are the genotypes of type A blood? ,
What are the genotypes of type B blood? ,
What is the genotype of AB blood?
What is the genotype of type O blood?
What are the genotypes of type A blood? ,

What is the genotype of AB blood?
What is the genotype of type O blood?

The genotypes for the different blood types based on the alleles \( I^A \), \( I^B \), and \( i \) are as follows:
1. **Type A blood**: The possible genotypes are:
- \( I^A I^A \) (homozygous)
- \( I^A i \) (heterozygous)
2. **Type B blood**: The possible genotypes are:
- \( I^B I^B \) (homozygous)
- \( I^B i \) (heterozygous)
3. **Type AB blood**: The genotype is:
- \( I^A I^B \) (heterozygous, expressing both alleles)
4. **Type O blood**: The genotype is:
- \( ii \) (homozygous recessive)
In summary:
- Type A: \( I^A I^A \) or \( I^A i \)
- Type B: \( I^B I^B \) or \( I^B i \)
- Type AB: \( I^A I^B \)
- Type O: \( ii \)
1. **Type A blood**: The possible genotypes are:
- \( I^A I^A \) (homozygous)
- \( I^A i \) (heterozygous)
2. **Type B blood**: The possible genotypes are:

- \( I^B i \) (heterozygous)
3. **Type AB blood**: The genotype is:
- \( I^A I^B \) (heterozygous, expressing both alleles)
4. **Type O blood**: The genotype is:
- \( ii \) (homozygous recessive)
In summary:
- Type A: \( I^A I^A \) or \( I^A i \)
- Type B: \( I^B I^B \) or \( I^B i \)
- Type AB: \( I^A I^B \)
- Type O: \( ii \)
