What did Mendel observe in the first generation (F1) of the pea plant cross?
What did Mendel observe in the first generation (F1) of the pea plant cross?
- All offspring had wrinkled yellow seeds.
- All offspring had round yellow seeds. (correct)
- The offspring displayed a mixture of traits, with some having round yellow seeds and others having wrinkled green seeds.
- All offspring had round green seeds.
What did Mendel discover by self-pollinating the F1 generation?
What did Mendel discover by self-pollinating the F1 generation?
- The traits of seed shape and color are linked and always inherited together.
- The F2 generation displayed only wrinkled green seeds.
- The traits of seed shape and color are not linked and are inherited independently of each other. (correct)
- The F2 generation displayed only round yellow seeds.

Study Notes
Mendel's Pea Plant Experiment
- Mendel crossed pea plants with round yellow seeds and green wrinkled seeds.
- The first generation (F1) offspring all had round yellow seeds.
- Mendel self-pollinated the F1 plants to investigate the recessive traits of wrinkled and green seeds.
- The second generation (F2) showed new combinations of traits, alongside the original traits.
- This indicated that seed shape and color are inherited independently.
