AOne half
BOne tenth
COne quarter
DOne eighth
Answer & Solution
Correct answer: C. One quarter
1. The F1 plants were all tall, but they carried both traits.
2. The F2 progeny of the F1 tall plants are not all tall; one quarter of them are short.
3. So both tallness and shortness were inherited, but only tallness was expressed.
