Explanation:
Detailed explanation-1: -Vegetative propagation does not involve fusion of gametes, thus recombination of characters from different sources (parents) does not occur. Hence, it cannot be used to introduce good genetic traits in the species.
Detailed explanation-2: -A significant drawback of vegetative propagation is that it prevents genetic diversity of species that may lead to crop yield decreases. The plants are genetically identical and are therefore all prone to pathogenic plant viruses, bacteria and pillows which can wipe out whole crops. Was this answer helpful?
Detailed explanation-3: -Flower of any plant is involved in sexual reproduction, and hence is not involved in vegetative propagation.
