Q. In a dihybrid cross, the maximum number of phenotypes would be

Principles of Inheritance and Variation

Solution:

Monohybrid cross produces $2$ phenotypes
Dihybrid cross productes $4$ phenotypes
Trihybrid cross produces $8$ phenotypes
Total number of phenotypes $= 2^n$
Total number of genotypes $= 3^n$
Where $n = $ type of cross (for monohybrid $n = 1$, for dihybrid $n = 2$ and....so, on)
