Question

How to find F1 and F2

Answer 1

Answer:

Monohybrid cross

Explanation:

Let you want to cross tall and short

Let tall be : TT

Let short be : tt

TT×tt

After crossing

F1 : Tt,Tt,Tt,Tt

So in F1 generation all are tall

Now we can cross F1

Tt×Tt

After crossing we get

F2 : TT,Tt,Tt,tt

So in F2 generation we get 1 tall plant,2 medium tall plants and 1 short/dwarf plant

Phenotypic ratio is 3:1

Genotypic ratio is 1:2:1

So I hope you understood
