So the gametes produced by the tall plant are Ts and ts. The gametes produced by the dwarf plant are tS and ts
So just line them up
      ----- tS  ---  ts
Ts TtSs       Tsts
 ts tSts        tsts
Therefore 1/4 would be TstS 1/4 would be Tsts 1/4 would be tstS and 1/4 would be tsts.

This is a 2x2 Punnett square:
_____Ts_____ts___
tS__TtSs___ttSs___
ts__Ttss___ttss____

Both genotypic and phenotypic ratios are 1:1:1:1 assuming completely independent assortment/no linkage.
