Solution
The correct option is C 3 In a monohybrid cross, total 3 genotypes are there in F2 generation. For example, the cross between pureline tall (TT) and dwarf (tt) plants have been shown below:
The genotypic ratio is:
TT : Tt : tt =1 : 2 : 1
Hence, the total number of different types of genotypes = 3.
