What is ratio of f1 and f2 generation ? For experiment of pea plant.

Solution

If you
See the above punnet square, you will see that the tall and short plant is giving all tall plants in first generation.
First generation is called F1 generation.So 100% tall.
When F1 individuals (Tt) are crossed , they give rise to F2 generation.
In the F2 generation, we get 3 tall plants and 1 short plant.So te ratio of F2 generation here is 3 tall and 1 sort.
We say it 3:1 ratio.
Hope this will make you understand.
