The original generation of pea plants in Mendelβs experiment were the parental generation, known as the P generation. Mendel selected specific pea plants with contrasting traits, such as tall and short, to cross-pollinate and observe how these traits were inherited in subsequent generations.
f2 generation
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.
In Mendel's first experiment with pea plants, he crossed true-breeding plants with contrasting traits (e.g., tall and short). He found that the first generation (F1) offspring all displayed one of the traits, while the second generation (F2) showed a 3:1 ratio of the dominant to recessive trait. This led him to formulate his principles of inheritance, now known as Mendelian genetics.
The offspring produced by crossing F1 plants is known as F2 generation. This generation results from the self-pollination of F1 hybrid plants. The F2 generation exhibits greater genetic variability due to the recombination of alleles from the original parental lines.
To get the F2 generation from the F1 generation, you cross two F1 individuals together. The offspring of this cross will represent the F2 generation. In Mendelian genetics, the F2 generation allows you to observe the genotypic and phenotypic ratios resulting from the recombination of alleles.

There were three times as many tall plants as short plants.
