Question

in one his experiments with pea plants mendel observed that when a pure tall plants is crossed with a pure dwarf pea plant in the first generation f1 only tall pkants appear (a) what happens to the traits of the dwarf in this case (b) when the f1 generation plants were self fertilised he observed that in the plants of second generation f2 both tall plants and dwarf plants were present why it happened ? explain verify

Answer 1

In the experiments on pea plant, tall trait is dominant and dwarf trait is recessive. Therefore, Tall trait will express in F1 generation and genotypes of all offsprings are Tt.
but this recessive dwarf character will express itself in F2 generation and genotypes of offsprings in F2 generation are 1 TT, 2 Tt, 1 tt.
