Question

Differentiate between spontaneous and induced mutations.

Answer 1

Aspect	Spontaneous Mutations	Induced Mutations
Origin	They originate spontaneously in nature without human intervention.	They are artificially induced by humans using mutagenic agents.
Occurrence	Continuously arise automatically in nature.	Occur only when man artificially induces them; otherwise not found naturally.
Cause	Produced by naturally occurring mutagenic agents such as electric currents, atomic particles and rays, temperature variations, etc.	Produced by subjecting organisms artificially to mutagens such as gamma rays, X-rays, neutrons, ultraviolet rays, etc.
Frequency	Frequency of occurrence is very low.	Frequency of occurrence is comparatively higher.
