Question
Bring out the drawbacks of the artificial systems of classification.
✓

Answer

  1. Artificial systems have separated the closely related species, as they consider only a few superficial characters.
  2. Artificial systems give equal weightage to both vegetative and sexual/ reproductive characters; this is not acceptable, because the vegetative characters are easily affected by changes in the environment.
