Question

Somaclones are obtained by
A. Irradiation
B. Genetic engineering
C. Tissue culture
D. Plant breeding

Answer 1

Hint: Plant tissue culture is a technique collection which helps us in the growth and maintenance of the plants in some sterile medium of nutrients composition.

Complete answer:
As the name indicates these are the somatic clones so these are basically the plant clones in which from a single tissue we can generate a whole plant. The parent plant and the new plant are the clones of each other. So these clones are prepared via the tissue culture technique which are identical to the parent progeny from which the tissue culture has been prepared.
Tissue culture helps us in the production of new individuals without even any pollinator or seed available at that time. The basic need in creating tissue culture technique includes : aseptic condition, aeration of the media and the nutrient broth. Tissue culture is a type of in vitro culture.
It is produced through micropropagation which is a technique by which we take the tissue culture and we get the plant let for others this plant is kept for growing in the soil. So, these clones are both genetically and morphologically similar. Some advantages of this somaclones technique is it is a very fast method by which we can grow money plants in a large number in a very small period of time.
Here we can make non diseased plants out of diseased plants without taking out the tissue from the apical Meristem because it is an actively dividing tissue so as we know why it requires the slow dividing tissue to replicate itself.

The correct option is C.

Note: So, genetic variation arises by plant tissue culture technique full stop; they are detected by genetic or epigenetically changes in your own DNA.
