Question

Which among the following is/are demerits of vegetative propagation?

• A. There are no genetic variations.
• B. This includes overcrowding.
• C. The diseases of the parent plant gets transferred to offspring.
• D. All of the above

Answer 1

The correct option is D

All of the above

Vegetative propagation:

1. Vegetative propagation is a type of asexual reproduction in which a new plant grows from a cutting-off or fragment of a parent plant.
2. Grafting, layering, cutting, stolon formation, suckering, tissue culture, etc are types of vegetative propagation.

The correct option is D.

Explanation for correct option:

Option A:

1. Vegetative propagation involves the growth of new individuals who are genetically identical to their parents.
2. As they are genetically identical to their parents there are no genetic variations seen in vegetative propagation.

Option B:

Vegetative propagation includes overcrowding due to which severe competition between the members of the same species is seen.

Option C:

As there is no genetic variability in vegetative propagation the disease-causing genes from the parent can be transferred to the offspring.

Final answer: No genetic variations, overcrowding or transfer of diseases from parent to offspring are all demerits of vegetative propagation.
