Question

If we cross-bred tall (dominant) pea plant with pure bred dwarf (recessive) pea plant, we will get plants of F₁ generation. If we now self-cross the pea plant of F₁ generation, we obtain pea plants of F₂ generation.

(i) What do the plants of F₁ generation look like ?
(ii) State the ratio of tall plants to dwarf plants in F₂ generation.
(iii) State the type of plants not found in F₁ generation but appeared in F₂ generation. Write the reason for the same.

Answer 1

(i) Tall
(ii) 3:1
(iii) Dwarf
Reason: Being a recessive trait, dwarfness can only be expressed in the absence of dominant trait/ in its pure form.
