Solution
The correct option is C 1 : 2 : 1
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’.
