A tall true breeding garden pea plant is crossed with a dwarf true breeding garden pea plant. When the F_{1} plants were selfed the resulting genotypes were in the ratio of:

Solution & Step-by-step Explanation

Cross: TT \times tt \to F_{1} : Tt (Tall).Selfing F_{1} : Tt \times Tt \to 1 TT : 2 Tt : 1 tt .The genotypic ratio is 1 Tall homozygous (TT) : 2 Tall heterozygous (Tt) : 1 Dwarf (tt).

Try it yourself before checking the explanation above.

A tall true breeding garden pea plant is crossed with a dwarf true breeding garden pea plant. When the F_{1} plants were selfed the resulting genotypes were in the ratio of:

1 : 2 : 1 :: Tall heterozygous : Tall homozygous : Dwarf

3 : 1 :: Tall : Dwarf

3 : 1 :: Dwarf : Tall

1 : 2 : 1 :: Tall homozygous : Tall heterozygous : Dwarf
