Answer: 4
Explanation:
If six genotypes are present then 4 phenotypes are exhibited because in two cases 'i' is inherited along with IA and IB.
Since IA and IB are dominant, 'i' becomes recessive and the phenotype becomes similar to IAIA and IBIB respectively.
I hope this helps.
Feel free to ask incase your doubt is still not cleared.
