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.

In Mendel's experiments, recessive traits were visible in the F2 generation. After crossing two purebred plants (P generation), the F1 generation exhibited only the dominant traits. However, when the F1 plants were self-pollinated, the F2 generation displayed a 3:1 ratio of dominant to recessive traits, revealing the recessive traits in a subset of the plants.
