Question

if we cross pure bred-tall pea plant with pure bred-dwarf pea plant wa will get pea plant ofF1 generation.If we now self cross the pea plant of f1 generation,then we obtain pea plant of f2 generation a)what do the plants of f1 generation look like?

Answer 1

a) The plants of F generation will look tall.

(b) The ratio of tall plants to dwarf plants in F2 generation is: 3:1

(c) Dwarf plants are not found in F1generation but appeared in F2generation. In the F1 generation, the dominant characteristic is Tall which appeared in F1 progeny but in F2generation, presence of two recessive characteristics/ traits, the plants which appeared are dwarf.

Answer 2

In f1 generation we will get tall pea plant. In which contain both dominat and recessive but dominant is expressed because in f1 progeny tall is dominant
