Question

Chromosomal Theory of Inheritance was proposed by:

• A. Jacob and Monad
• B. Mendel and Strassberger
• C. Sutton and Boveri
• D. Muller and Jacob

Hint:

Chromosomal Theory:
- Proposed by Sutton and Boveri (1902).
- Chromosomes are the carriers of genes.
- Based on the parallelism between chromosome behavior and Mendelian inheritance.

Answer 1

The Correct Option is C

Step 1: Understanding the Question:
This question tests knowledge of the history of genetics.

Step 2: Detailed Explanation:
The Chromosomal Theory of Inheritance was proposed independently by Walter Sutton and Theodor Boveri in 1902.
They proposed that chromosomes are the carriers of genetic information.
Jacob and Monad (A): Proposed the operon model.
Mendel and Strassberger (B): Mendel proposed laws of inheritance, Strassberger studied chromosomes.
Muller and Jacob (D): Muller studied mutations, Jacob studied operon.
Thus, Sutton and Boveri proposed the Chromosomal Theory.

Step 3: Final Answer:
Thus, the Chromosomal Theory of Inheritance was proposed by Sutton and Boveri, which corresponds to option (C).
