Recessive traits were visible in the F2 generation of Mendel's experiments, where the offspring of the F1 generation showed a 3:1 ratio of dominant to recessive traits.

The off spring is shown the alleles for seed shape segregate independently for seed color because one allele isn't completely dominant over the other. This is taught in biology.
In Mendel's experiments, recessive traits were visible in the F2 generation. After crossing true-breeding plants in the F1 generation, which displayed only dominant traits, the recessive traits reappeared in a ratio of approximately 3:1 in the F2 generation. This observation was crucial for Mendel's formulation of the laws of inheritance.
9:3:3:1 was the ratio of Mendel's f2 generation for the two factor cross.
In a typical Mendel experiment, Mendel took two purebreeding lines (the parental generation) and crossed them to produce the 1st filial generation and sometimes would self cross these to produce the 2nd filial generation.
