Question
Write the objections to Mutation theory of Hugo de Vries.
✓
Answer
Objections to Mutation Theory:
- Hugo de Vries observed the large and discontinuous variation. But these were chromosomal aberrations. Only gene mutations usually bring about minor changes.
- Rate by which mutations take place is very slow as compared to the requirement of evolution.
- Chromosomal aberrations are very unstable.
- The organisms with chromosomal aberration are usually sterile and thus chromosomal aberrations have little significance in evolution.
