When a pair of contrasting characters is present together, only one trait appears in the first generation. This expressed trait is called dominant trait and the unexpressed trait is called the recessive trait.
For example, when Mendel crossed a pure breed tall pea plant with a pure breed dwarf plant. He found that all the plants in the F1 generation were tall. That means, only tallness trait appeared in the F1 generation. Thus, it was the dominant trait while dwarfness was the recessive trait.

Answer:
Mendel took tall pea plants and short pea plants and produced F1 progeny through cross fertilisation the resultant progeny are in 3:1 ratio. 3 tall plants and 1 short plant.
Explanation:
Mendel took tall pea plants with genotype TT and short pea plants with genotype tt and produced F1 progeny through cross fertilisation the resultant progeny are in 3:1 ratio. 3 tall plants and 1 short plant.
TT ( tall ) * tt (short) → 3 tall ( TT, Tt, Tt ) : 1 short (tt)
