Q10 / 68 · NEST (NISER) 2023 (Session 2) · Biology
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).
- Correct answerAF2 progeny will have $\frac{1}{4}$ probability of showing the parental phenotype.
- Correct answerB$50 \%$ of the progeny in the F2 generation will be pink in colour.
- Correct answerCIn F2 progeny, peloric-shaped flowers with pink colour are expected to be in $\frac{1}{8}$ ratio.
- DIn F2 progeny, the ratio of red-coloured personate-shaped flowers would be $\frac{1}{4}$.
Hence, the correct answer is options: 'A', 'B', 'C'.
