D. Quantitative genetics

Answer

**Step-by-Step Solution:**

1. **Identify the Subject of the Question**: The question asks about Walter Sutton and his contributions to biology.

2. **Review the Options Provided**: The options are:
- A) Chromosomal theory of inheritance
- B) Genetic engineering
- C) Totipotency
- D) Qualitative genetics

3. **Recall Historical Context**: Walter Sutton made significant contributions to genetics in the early 20th century, specifically in 1902.

4. **Understand Sutton's Key Contribution**: At the age of 25, Sutton proposed that chromosomes are the basis of heredity. He linked the behavior of chromosomes during meiosis to Mendel's laws of inheritance.

5. **Conclude the Theory**: Sutton, along with another scientist named Bobi, formulated the chromosomal theory of inheritance, which states that genes are located on chromosomes and that the segregation of chromosomes during meiosis is responsible for inheritance patterns.

6. **Select the Correct Answer**: Based on the information, the correct answer to the question "Walter Sutton is famous for his contribution to" is option A) Chromosomal theory of inheritance.

**Final Answer**: Walter Sutton is famous for his contribution to the chromosomal theory of inheritance.
