List any two pairs of visible contrasting characters of garden pea plants used by Mendel for his experiments stating the dominant and recessive characters in each pair.
Step 1: Pair 1 - Flower Colour:
- Mendel used the contrasting characters of flower colour in garden pea plants for his experiments.
- Dominant character: Purple flower colour (P).
- Recessive character: White flower colour (p).
Step 2: Pair 2 - Seed Shape:
- Another contrasting character Mendel studied was the shape of the seeds in garden pea plants.
- Dominant character: Round seeds (R).
- Recessive character: Wrinkled seeds (r).
Step 3: Conclusion:
Mendel studied the inheritance of various visible contrasting characters in garden pea plants, such as flower colour and seed shape. The dominant and recessive traits in these pairs were:
1. Flower colour: Purple (dominant) vs. White (recessive).
2. Seed shape: Round (dominant) vs. Wrinkled (recessive).
