Monohybrid F2 (Tt × Tt):

	T	t
T	TT (Tall)	Tt (Tall)
t	Tt (Tall)	tt (Dwarf)

Result: 3 Tall : 1 Dwarf (phenotypic); 1 TT : 2 Tt : 1 tt (genotypic)

Dihybrid F2 phenotypic class distribution (TtRr × TtRr):

Phenotype	Cells (out of 16)	Fraction
Tall Round ( $T_R_$ )	9	9/16
Tall Wrinkled ( $T_{rr}$ )	3	3/16
Dwarf Round (ttR_)	3	3/16
Dwarf Wrinkled (ttrr)	1	1/16
