(A) To determine the offspring,we perform a dihybrid cross between $TtRr$ and $TTrr$.$1$. Gametes produced by $TtRr$: $TR, Tr, tR, tr$.$2$. Gametes produced by $TTrr$: $Tr$.$3$. Crossing these gametes results in the following genotypes:- $TR \times Tr = TTRr$ (Tall pink)- $Tr \times Tr = TTrr$ (Tall white)- $tR \times Tr = TtRr$ (Tall pink)- $tr \times Tr = Ttrr$ (Tall white)Thus,the offspring produced are tall pink and tall white plants.

A
Tall pink and tall white
B
Dwarf pink and tall red
C
Dwarf red and tall pink
D
Tall pink and dwarf white
