F3 generation for a dihybrid?

Let's say we have Tall(TT) and dwarf(tt).

At the end of the F2 generation you have the offspring TT Tt Tt tt in which the genotypic ratio is 1:2:1 and phenotypic ratio is 3:1.

You have to use four charts, one for each genotype pairing with another.

.....T......T
T..TT....TT
t...Tt.....Tt

.....T.....T
t...Tt.....Tt
t...Tt....Tt

.....T......t
T..TT....Tt
t...Tt.....tt

.....T.....t
t...Tt....tt
t...Tt....tt

The single letters are the gametes. Hope you can make sense out of it. These should be all possible genotypes in the F3 generation resulting from a pairing of the individuals of the F2 generation.
