Question

a pure tall plant (TT) is created with pure drawf plant(tt) what would be the F1 and F2 geberation?explain?​

Answer 1

Explanation:

HEY MATE HERE IS YOUR ANSWER

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.

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 – tall homozygous:tall heterozygous:dwarf’.
