Write 2 disadvantages of vegetative propogation?

Vegetative propagation is a type of asexual reproduction of a plant where only a single plant is involved. Parts (Stems, Roots, Leaves and Bulbs) of plants by the process (Cutting, grafting and layering) can form a new plant which is genetically identical to its parent plant.

Disadvantage:

New characters can neither be introduced nor undesirable characters be eliminated.

The plants cannot withstand unfavorable condition as there is no genetic variation.

The disease of the parent plant gets transferred to the offspring.
