In peas, a pure tall plant (TT) is crossed with a pure short plant (tt). The ratio of pure tall plants to pure short plants in F2 generation will be:(a) 1:3 (b) 3:1 (c) 1:1 (d) 2:1 36698"
Correct Answer : (c) 1:1
Explanation :
In pea plant, when pure tall pea plant (TT) is crossed with pure short (tt) plant,
F1 generation will be all Tt (tall plant).
(Pure Tall) TT x tt (Pure short)
F1 generation Tt (All tall plant)
Self-pollination Tt x Tt
F2 generation TT Tt Tt tt
1 2 1
Thus, the ratio of pure tall plants (TT) to pure short plants (tt) is 1:1 .
