Question
How many per cent of hybrid tall plants do we get in F₁ generation, if pure dwarf plant (tt) is crossed with hybrid tall plant (Tt) ?
- 25%
- 50 %
- 75%
- 100%.
Answer
50%
Explanation:
In a monohybrid cross between a pure dwarf plant (tt) and a hybrid tall plant (Tt), all the F₁ plants will be Tt genotype. Since tallness is dominant, all the F₁ plants will be tall. Therefore, the percentage of hybrid tall plants in the F₁ generation will be 50%.
