Solution

Number of different F2 phenotypes (complete dominance)

2ⁿ

Number of different F2 genotypes (or phenotypes, if no dominance)

Number of different F2 genotypes = 3^n
And phenotypes =2^n
It is tri hybrid.... So n=3

There fore total number of genotypes+phenotypes=3^3 + 2^3=35
So 35 is the answer
