In Mendel's experiments, recessive traits were hidden in the F1 generation. When he crossed pure-breeding plants with contrasting traits, all offspring in the F1 generation exhibited the dominant trait. It was only in the F2 generation, produced by self-pollinating the F1 plants, that the recessive traits reappeared in a 3:1 ratio alongside the dominant traits.
In Mendel's experiments, the recessive traits were observed in the F2 generation. Initially, the traits were not visible in the F1 generation, where only the dominant traits were expressed. However, when the F1 plants were allowed to self-pollinate, the recessive traits reappeared in the F2 generation, typically in a ratio of about 3:1, dominant to recessive.
In Mendel's experiments with pea plants, the ratio of tall to short plants in the F1 generation was 100% tall, as tall (dominant) traits masked the short (recessive) traits. However, in the F2 generation, after self-pollinating the F1 plants, the ratio of tall to short plants was approximately 3:1, with three tall plants for every one short plant.
When a first generation plant self pollinates, the ratio of dominant to recessive traits in the second generation plants is typically 3:1. This is based on Mendel's principle of segregation, which predicts that in a monohybrid cross, three plants will exhibit the dominant trait and one will exhibit the recessive trait.

In Mendel's experiment, the ratio of tall to short plants in the F2 generation was approximately 3:1. This ratio is explained by Mendel's law of segregation, which states that alleles separate randomly during gamete formation, resulting in different combinations in offspring.
