Question

A pure tall plant (TT) is crossed with the pure dwarf plant (tt), what would be the F1 and F2 generations? Explain.

Short Note

Solution

When a pure tall plant (TT) is crossed with the pure dwarf plant (tt), In F1 generation all the plants will be tall. In F2 generation by selling the F1 monohybrid the tall and dwarf plant will be in the ratio of 3 : 1. In the F2 generation phenotypic ratio will be 3 : 1. the genotypic ratio will be 1 : 2 : 1.
