Options

A. Alternative forms
B. contrasting traits
C. mixed forms
D. opposite and recessive forms

Answer

### Step-by-Step Solution:

1. **Identify the Subject**: The question asks about the traits described by Gregor Mendel in his genetic studies.

2. **Understand Mendel's Work**: Mendel is known as the father of genetics and conducted experiments on the garden pea plant, scientifically known as *Pisum sativum*.

3. **Define Traits**: Mendel studied various traits, which are characteristics that can be observed in organisms. These traits can show different forms.

4. **Contrasting Traits**: Mendel specifically focused on contrasting traits, which are pairs of traits that are opposite to each other. For example, in terms of plant height, the contrasting traits are tall and short.

5. **Examples of Contrasting Traits**: Mendel identified seven pairs of contrasting traits in garden peas, such as:
- Tall vs. Dwarf (height)
- Yellow vs. Green (seed color)
- Round vs. Wrinkled (seed shape)
- etc.

6. **Conclusion**: Based on Mendel's studies, the traits he described were indeed contrasting traits, as they represent different forms of the same character.

7. **Final Answer**: Therefore, the answer to the question is that the traits described by Mendel were **contrasting traits**.
