In a true-breeding homozygous lines of snapdragon, Antirrhinium majus, white coloured flower of personate shape was crossed with red coloured flower with peloric shape. The F1 flowers were pink and personate-shaped. Assuming that both these genes segregate independently, choose the correct option(s).

Options

  1. AF2 progeny will have 1 4 probability of showing the parental phenotype.
  2. B50 % of the progeny in the F2 generation will be pink in colour.
  3. CIn F2 progeny, peloric-shaped flowers with pink colour are expected to be in 1 8 ratio.
  4. DIn F2 progeny, the ratio of red-coloured personate-shaped flowers would be 1 4 .

Correct answer

C. In F2 progeny, peloric-shaped flowers with pink colour are expected to be in 1 8 ratio.
