Just remember the Genotypic ratio is the no. of different genes i.e. In Tt TT tt, there are 3 genotypes
And Phenotypic ratio is the ratio of no. of traits, like in the same above example, TT and Tt shows similar character hence, it is counted as 1 trait
Therefore, out of TT Tt and tt, there are 2 Phentypes
