When Mendel crossed tall and dwarf plants, the F2 generation showed both traits in a 3:1 ratio. This proved that:
Show answer and explanation
Correct answer: The 'dwarf' factor was merely hidden in F1 by the 'tall' factor.
The reappearance of the recessive trait in the F2 generation disproved the 'blending inheritance' theory. It showed that discrete hereditary units (genes) remain intact and unmixed through generations.
