What percentage of tall plants will be found in the first generation?
Think it through first, then pick an option.
- a 100
- b 75
- c 50
- d 25
Answer and explanation
Correct answer: a 100
In the first generation all plants are tall (dominant), so 100%.
Why the other options are wrong
- b 75: 75% is the share of tall plants in the second generation.
- c 50: Not 50%; in the first generation every plant is tall.
- d 25: 25% is the share of short plants in the second generation.
