Which organism did Mendel settle on as the primary model system for his inheritance work?
AThe honeybee
BThe fruit fly
CThe garden pea
DThe snapdragon
Answer & Solution
Correct answer: C. The garden pea
1. Mendel began in 1856 with inheritance patterns in honeybees and plants.
2. He ultimately settled on pea plants as his primary model system.
3. Fruit flies became a model organism for later workers, not for Mendel.
4. Snapdragons appear as an example of incomplete dominance, not as Mendel's model.
