Question

The chromosome theory was proposed by

• A. Theodor Boveri
• B. Thomas Hunt Morgan
• C. W. S. Sutton
• D. Sutton and Boveri

Answer 1

The correct option is D Sutton and Boveri

The chromosome theory of inheritance is credited to papers by Walter Sutton in 1902 and 1903, as well as to independent work by Theodor Boveri during roughly the same period. The Boveri–Sutton chromosome theory is a fundamental unifying theory of genetics which identifies chromosomes as the carriers of genetic material. It correctly explains the mechanism underlying the laws of Mendelian inheritance by identifying chromosomes with the paired factors (particles) required by Mendel's laws. It also states that chromosomes are linear structures with genes located at specific sites called loci along them.

So, the correct answer is 'Sutton and Boveri'.
