The first generation of of pea plants that Mendel bred were tall.
In the first-generation plants, the height may vary due to genetic recombination from the parent plants. In the second-generation plants, the height will tend to show more consistency as the offspring inherit a mix of genetic traits from the first-generation plants, resulting in a more predictable range of heights.

The first generation of offspring in Mendel's experiments are called the F1 generation or the first filial generation. These are the offspring resulting from the crossing of two parental or P generation plants.

no. in the second generation it will have a short offspring , but in the first generation it will have tall offspring
F1
All of Mendel's first-generation plants were tall because they were all homozygous dominant for the trait of tallness. This means they received two dominant alleles for tallness from the parental plants, resulting in expression of the tall phenotype.
f2 generation
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.
