All are dominant traits studied by Mendel

Options

A. Green pod, Inflated, pod, axial flower
B. Round seed, constricted pod, axial flower
C. Yellow seed, violet flower, yellow pod
D. Axial flower, gree pod, green seed

Answer

### Step-by-Step Solution:

1. **Understanding Dominant Traits**:
- Dominant traits are those that are fully expressed in the phenotype of an organism and can mask the presence of recessive traits.

2. **Mendel's Experimentation**:
- Gregor Mendel conducted experiments on the pea plant, *Pisum sativum*, and identified several traits that exhibited dominant and recessive patterns.

3. **Identifying the Dominant Traits Studied by Mendel**:
- Mendel studied seven traits in total, but we are focusing on the dominant traits:
- **Seed Shape**: Round (dominant)
- **Seed Color**: Yellow (dominant)
- **Flower Color**: Purple (dominant)
- **Flower Position**: Axial (dominant)
- **Plant Height**: Tall (dominant)
- **Pod Shape**: Inflated (dominant)
- **Pod Color**: Green (dominant)

4. **Evaluating the Options**:
- We need to identify which of the provided options include only dominant traits.
- The options provided include combinations of traits, and we must check each one against the list of dominant traits.

5. **Correct Option Identification**:
- The first option includes green pod, inflated pod, and axial flower. All of these traits are dominant.
- The second option includes round seed but constricted pod, which is incorrect as constricted pod is recessive.
- The third option includes yellow seed and green pod, which is incorrect as the combination is not fully dominant.
- The fourth option includes green pod and yellow seed, which is also incorrect for the same reason.

6. **Conclusion**:
- The correct answer is the first option: green pod, inflated pod, and axial flower, as all these traits are dominant traits studied by Mendel.
