Question

In peas a pure tall plant (IT) is crossed with a hybrid tall plant (Tt) what will be the ratio of pure tall plants to the hybrid tall plants​

Answer 1

Answer:

According to the question:

Parent generation TT (pure tall) x tt (pure dwarf)

gametes                   T                            t

F1​ generation  Tt (heterozygous tall)

F2​ generation

Gametes Tt--->

Tt  T  t

T  TT  Tt

t  Tt  tt

F2​ Genotypic ratio =1 pure tall (TT) : 2 heterozygous tall (Tt) : 1 pure dwarf (tt); thus, the ratio of pure tall to pure short plants will be 1:1.
