The correct Answer is:
To solve the question regarding which seed characters of Pisum sativum were studied by Mendel in his hybridization experiments, we will analyze each option based on Mendel's documented experiments. ### Step-by-Step Solution: 1. **Understand Mendel's Experiments**: Mendel conducted hybridization experiments using pea plants (Pisum sativum) and identified seven pairs of contrasting traits. These traits were crucial in establishing the laws of inheritance. 2. **Identify the Traits Studied by Mendel**: The traits Mendel studied included: - Plant height (tall vs. dwarf) - Seed shape (round vs. wrinkled) - Seed color (yellow vs. green) - Pod shape (inflated vs. constricted) - Flower color (purple vs. white) - Flower position (axial vs. terminal) - Seed coat color (gray vs. white) 3. **Evaluate Each Seed Character in the Question**: - **Seed Shape**: This was one of the traits Mendel studied (round vs. wrinkled). - **Seed Weight**: This was not one of the traits Mendel studied. - **Seed Coat Color**: This was one of the traits Mendel studied (gray vs. white). - **Seed Starch Grain Size**: This was not one of the traits Mendel studied. - **Seed Number**: This was not one of the traits Mendel studied. 4. **Select the Correct Options**: Based on the analysis: - Seed shape (1) and seed coat color (3) were studied by Mendel. - Therefore, the correct answer includes these two traits. 5. **Conclusion**: The correct answer is option 1, which includes seed shape and seed coat color. ### Final Answer: The seed characters of Pisum sativum studied by Mendel in his hybridization experiments are: - Seed Shape (1) - Seed Coat Color (3) **Correct Option**: 1 and 3.
