Question

Draw monohybrid cross between 1. Round and wrinkled seed 2. Tall and dwarf plants . also show their genotypic and phenotypic ratio​

Answer 1

Answer:

As a result of monohybrid cross among Pea plants, the genotypic ratio obtained by Mendel is __________.

Solution:

Mendel crossed pure tall plant(TT) with a pure dwarf plant(tt). In the F1 generation, tall plants are formed(Tt). When F1 plant is subjected to self pollination, in the F2 generation, 3 tall plants and 1 dwarf plants are formed. In the one homozygous tall plant (TT), 2 heterozygous tall plants(Tt), one homozygous dwarf plant(tt) are formed. Phenotypic ratio is 3:1, genotypic ratio is 1:2:1.

So, the correct option is ‘1:2:1’.
