Question

Give two difference between spontaneous and induced mutations.

Answer 1

Spontaneous mutations continuously arise in nature automatically, whereas induced mutations are man-made and, therefore occur when man induces them, otherwise never found.
Spontaneous mutations are produced by naturally occurring mutagenic agents such as electric currents, atomic particles and rays, temperature, variations, etc. whereas induced mutations are produced by subjecting organism artificially to mutagens such as gamma rays, X-rays, neutrons, ultraviolet rays, etc.
