A tall true breeding garden pea plant is crossed with a dwarf true breeding garden pea plant. When the F1 plants were selfed the resulting genotypes were in the ratio of
  • a)
    1 : 2 : 1 : : Tall homozygous : Tall heterozygous : Dwarf
  • b)
    1 : 2 : 1 : : Tall heterozygous : Tall homozygous : Dwarf
  • c)
    3 : 1 : : Tall : Dwarf
  • d)
    3 : 1 : : Dwarf : Tall
Correct answer is option 'A'. Can you explain this answer?

A tall true breeding garden pea plant is crossed with a dwarf true br...
Explanation:
First, it is important to understand the genetics of the garden pea plants involved in the cross.

Cross between Tall true breeding and Dwarf true breeding plants:
- Tall true breeding plant: TT
- Dwarf true breeding plant: tt

F1 generation:
- When a tall true breeding plant (TT) is crossed with a dwarf true breeding plant (tt), all the offspring in the F1 generation will be heterozygous for the tall trait (Tt).

Genotypes in F1 generation:
- All F1 plants will have the genotype Tt.

Selfing of F1 generation:
- When the F1 plants are selfed (crossed with each other), the genotypes of the offspring will be:
- Tall homozygous (TT): 1/4
- Tall heterozygous (Tt): 2/4
- Dwarf (tt): 1/4

Ratio of genotypes:
- The genotypes of the offspring after selfing the F1 generation will be in the ratio of 1 : 2 : 1:
- Tall homozygous : Tall heterozygous : Dwarf
Therefore, the correct answer is option 'A' - 1 : 2 : 1 : Tall homozygous : Tall heterozygous : Dwarf.
