1. When a tall plant was crossed with a short plant, the first(F1)generation plants were all tall.

2.But when the F1 generation plants were crossed, the second(F2)generation plantswere not all tall: there were both tall and short plants.
3.This shows that the F1 plantshad inherited their traitfrom the short plantsbut did not express it in the presence of the tallness, and had transferred it to the next generation.

When a tall pea plant was crossed with a dwarf pea plant, the $F_{1} $ generation plants were all tall. When $F_{1} $ plants were selfed, the $F_{2} $ generation plants were not all tall; they were tall and dwarf plants.
This shows that the $F_{1} $ plants had inherited both the parental traits but did not express dwarfness/recessive in the presence of the trait for tallness/dominant.
