Worked practice questions
A true-breeding pea line shows stable traits after continuous:
- Cross-pollination
- Vegetative propagation
- Self-pollination
- Repeated grafting
Show answer and solution
Correct answer: C. Self-pollination
A true-breeding line keeps the same trait for generations because it has undergone continuous self-pollination.
Which pod shape traits formed one of Mendel's contrasting pairs in pea?
- Inflated or constricted
- Straight or sickle-shaped
- Broad or narrow-tipped
- Smooth or deeply ridged
Show answer and solution
Correct answer: A. Inflated or constricted
Pod shape in Mendel's pea was either inflated or constricted.
