A true-breeding pea plant is one that does what?
AProduces only sterile seeds each season
BProduces gametes that carry no alleles
CProduces twice the normal seed number
DProduces offspring that look like the parent
Answer & Solution
Correct answer: D. Produces offspring that look like the parent
1. True-breeding lines arise from repeated self-fertilisation, which makes them highly inbred.
2. Such plants always produce offspring that look like the parent.
3. Sterile seed and doubled seed number describe fertility, not breeding true.
4. Gametes always carry alleles, so that option describes nothing real.
