Who gave chromosomal theory of inheritance ?

Options

A. Wilson and Stevens
B. Morgan
C. Sutton and Boveri
D. Bateson and Punnet

Answer

**Step-by-Step Solution:**

1. **Identify the Question**: The question asks for the scientists who proposed the chromosomal theory of inheritance.

2. **Understanding the Chromosomal Theory of Inheritance**: This theory states that chromosomes are the carriers of genetic material and that the behavior of chromosomes during cell division is parallel to the behavior of genes.

3. **Key Scientists Involved**: The main scientists associated with the development of the chromosomal theory of inheritance are Walter Sutton and Theodor Boveri.

4. **Explanation of Their Contribution**: Sutton and Boveri observed the behavior of chromosomes during meiosis and mitosis. They noted that the segregation of chromosomes during these processes is similar to the segregation of traits as described by Mendel's laws of inheritance.

5. **Conclusion**: Therefore, the chromosomal theory of inheritance was proposed by Walter Sutton and Theodor Boveri.

**Final Answer**: Walter Sutton and Theodor Boveri.
