When a cross is made between a tall plant with yellow seeds (Tt Yy) and a tall plant with green seeds (Tt yy), what is true regarding the proportions of phenotypes of the offsprings in `F_(1)` generation ?

A

`{:("Proportion of Tall and Green proportion of Dwarf and Green"),( (3)/(8)" "(1)/(8)):}`

B

`{:("Proportion of Tall and Green proportion of Dwarf and Green"),( (2)/(8)" "(1)/(8)):}`

C

`{:("Proportion of Tall and Green proportion of Dwarf and Green"),( (1)/(8)" "(3)/(8)):}`

D

`{:("Proportion of Tall and Green proportion of Dwarf and Green"),( (2)/(8)" "(2)/(8)):}`

Verified by Experts

The correct Answer is:
A
A cross between a tall plant with yellow seeds (TtYy) and a tall plant with green seeds (Ttyy) will be :

Pnenotypic ratio is
Tall and yellow : Tall and green : Dwarf and yellow : Dwarf and green :: 3 : 3: 1: 1 or 3/8, 3/8,1/8,1/8.
