Question

What type of progeny was obtained by Mendel in first and second
generations when he crossed the tall and short plants?​

Answer 1

Answer:

Mendel took a pure tall plant (TT) and crossed it with a dwarf (tt) plant. The progeny thus obtained was called F1 progeny (First filial progeny). Then he self pollinated the F1 progeny to obtain F2 generation. In F2 generation he found that 75% plants were tall and 25% were dwarf.

Explanation:

When Mendel crossed tall and short plants, the progeny obtained in Fl generation was tall. When the Fl plants were selfed, the F2 generation showed three tall and one dwarf plants. The genotypic ratio of F2 generation is 1: 2: 1 (TT: Tt: Tt: tt) and the phenotypic ratio is 3: 1 (Tall: Dwarf).
