in what ways in vegetative propagation better than sexual reproduction
Answers
Here's the answer to your question
Vegetative propagation, the ability of plants to reproduce without sexual reproduction, by producing new plants from existing vegetative structures. For the betterment of preservable genes nd for quick processes, vegetative propagation should be preferred over sexual reproduction. Some of the major advantages of vegetative propagation are:
1.
The offsprings are genetically identical and therefore advantageous traits can be preserved.
2. Only one parent is required which eliminates the need for special mechanisms such as pollination, etc.
3. It is faster. This helps the organisms to increase in number at a rapid rate that balances the loss in number due to various causes.
4. 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.
5. Vegetative propagation is especially beneficial to the agriculturists and horticulturists. They can raise crops like bananas, sugarcane, potato, etc that do not produce viable seeds. The seedless varieties of fruits are also a result of vegetative propagation.
6. The modern technique of tissue culture can be used to grow virus-free plants.

The main advantage of vegetative propagation is that the progeny plants contain the genetic material of only one parent.
Clones of the parent plant are only produced.
For example, if we have a plant of desirable traits, the same plant can be reproduced by vegetative propagation if the growing propagation remains similar.
This technique is useful for commercial growers who want to produce only the plants with highest quality.
Vegetative propagation can ensure the consistency of a plant variety or crop variety for sale.
This process also helps to maintain consistent quality and taste of the products made from the plants or crops.
For example, some tea plants like the Zealong's tea plantations, the new tea plants are made from the cutting using the older plants to ensure uniform consistency in the taste and quality of the tea.
Vegetative propagation can save a lot of time and money for production of plants on a commercial scale.
For example, for a tea plant to grow big enough from a cutting it takes 3-4 years to be ready for harvest and processing. Growing of the same plant from seed would take even longer.
