. How did Mendel interpret his result to show that traits may be dominant or recessive? Describe briefly
Ans. i. In Mendel's experiment with pea plants, when he crossbred a pure tall pea plant when a pure dwarf pea plant, he found that the first generation F1 was of only tall plan Tallness is the dominant trait.
ii. Then he produced F2 generation by selfing of hybrids F1.
iii. In the F1 progeny, no dwarf plants were obtained. However in F 2 generation, both and dwarf plants were obtained in the ratio 3 : 2 respectively.
iv. He observed that even when not expressed in the first generation, alternate forms of a trait could retain their identify in the hybrid and could re-emerge in the next generation.
