Advantages
The offsprings are genetically identical and therefore advantageous traits can be preserved.
Only one parent is required which eliminates the need for special mechanisms such as pollination, etc.
It is faster. For example, bacteria can multiply every 20 minutes. This helps the organisms to increase in number at a rapid rate that balances the loss in number due to various causes.
Many plants are able to tide over unfavourable conditions. This is because of the presence of organs of asexual reproduction like the tubers, corm, bulbs, etc.
Vegetative propagation is especially beneficial to the agriculturists and horticulturists.

*The offsprings are genetically identical and therefore advantageous traits can be preserved.
*Only one parent is required which eliminates the need for special mechanisms such as pollination.
*The modern technique of tissue culture can be used to grow virus free plants.
DISADVANTAGES
*The plants usually lose their vigor as there is no genetic variations.They are more prone to diseases that are specific to the species.This results in the destruction of entire crop.
*Since many plants are are produced,it results in over crowding and lack of nutrients.
