Options

A. De Vries
B. Tschermak-seysenegg
C. Carl Correns
D. T.H. Morgan.

Answer

To answer the question "Name the scientist who converted Mendel's conclusions into principles of heredity," we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Context**: Understand that the question is asking about a scientist who built upon Gregor Mendel's foundational work in genetics.

2. **Review Mendel's Contributions**: Mendel is known for his experiments with pea plants, which led to the formulation of the laws of inheritance. His work laid the groundwork for modern genetics.

3. **Evaluate the Options**:
- **Option A: De Vries** - Known for the theory of mutation, but he did not convert Mendel's conclusions into principles of heredity. This option is incorrect.
- **Option B: Chermak and Sassenegg** - They rediscovered Mendel's laws but did not convert them into broader principles. This option is also incorrect.
- **Option C: Karl Correns** - He is recognized for integrating Mendel's findings into the principles of heredity. This option is correct.
- **Option D: Thomas Hunt Morgan** - He contributed to the understanding of genetic linkage but did not convert Mendel's conclusions. This option is incorrect.

4. **Conclusion**: Based on the evaluation of the options, the scientist who converted Mendel's conclusions into principles of heredity is **Karl Correns**.

### Final Answer:
**Karl Correns**
