Question

Who proposed the Chromosomal Theory of Inheritance?

• A. Mendel
• B. Sutton and Boveri
• C. Darwin
• D. Morgan

Hint:

The Chromosomal Theory of Inheritance, proposed by Sutton and Boveri, forms the basis of our modern understanding of genetics and heredity.

Answer 1

The Correct Option is B

Step 1: Understanding the Chromosomal Theory of Inheritance.
The Chromosomal Theory of Inheritance suggests that genes are located on chromosomes and that chromosomes are the carriers of genetic information. It was proposed by Sutton and Boveri in the early 20th century.
Step 2: Analysis of options.

• (A) Mendel: Incorrect. Mendel is known for his foundational work on the principles of heredity but did not propose the Chromosomal Theory of Inheritance.
• (B) Sutton and Boveri: Correct. They jointly proposed the Chromosomal Theory of Inheritance based on their work on chromosomes and genetics.
• (C) Darwin: Incorrect. Darwin is known for his theory of evolution, not the Chromosomal Theory of Inheritance.
• (D) Morgan: Incorrect. Morgan's work on fruit flies contributed to our understanding of genetics, but he did not propose the Chromosomal Theory of Inheritance.

Step 3: Conclusion.
The Chromosomal Theory of Inheritance was proposed by Sutton and Boveri. Final Answer:} Sutton and Boveri.
