उत्तर
In a cross between two phenotypically tall plants, some of the progeny may turn out to be phenotypically dwarf. It means that both parents are heterozygous (Tt). The cross is demonstrated below by a Punnett Square.
Genotype of Parents = Tt.
Genotypic ratios of progeny after F1 cross= TT, Tt, Tt, tt.
Phenotypic ratios= 1 TT+ 2 Tt: 1 tt or 3 Tall: 1 dwarf
Case 1: Both parents hetrozygous
