APlants grown from the first filial seed lot
BPlants that were discarded before flowering
CPlants used in the first-generation crosses
DPlants that failed to set any seed in year one
Answer & Solution
Correct answer: C. Plants used in the first-generation crosses
1. Plants used in first-generation crosses were called the parental generation.
2. Their seeds were grown the next season to give the first filial generation.
3. So the first filial plants are the offspring, not the parental generation.
4. Discarded plants and plants that set no seed contribute nothing to a cross.
