alleryWhose mutational theory of 1901 explained the reasons behind sudden hereditary changes?
AWalter Sutton
BGregor Mendel
CHugo de Vries
DColin McLeod
Answer & Solution
Correct answer: C. Hugo de Vries
1. Sudden changes in characters needed an explanation after Mendel's work.
2. In 1901 Hugo de Vries proposed the mutational theory for these sudden changes.
3. So the credit goes to de Vries.
4. Sutton observed paired chromosomes in 1902, a different contribution, so he is ruled out.
