In peas, a pure tall plants (TT) is crossed with a pure short plant (tt). The ratio of pure tall plants to pure short plants in $F_{2}$ generation will be :

(a) 1 : 3 (b) 3 : 1 (c) 1 : 1 (d) 2 : 1

Solution

(c) 1 : 1

In pea plants, a pure tall plant (TT) is crossed with a short plant (tt). The ratio of pure tall plant to short plants in $F_{2}$ is 1:1
Following combinations of genotype emerge is F2 generation : TT (1), tt (1) and Tt (2).
This shows that ratio of pure tall (TT) to pure short (tt) is 1:1.
