All the genetic mutations may occur spontaneously in organisms is t he incidence of such mutations may be increased by what?

Both physical and chemical factors

Explanation:

A mutation is any alteration in the DNA sequence of the genome of a particular cell/organism. Depending on the type and localization, a mutation can be neutral, deleterious, or even beneficial for the individual that possesses it. Moreover, the mutation rate refers to the probability for a mutation to appear in a cell/organism. Exposure to physical environmental factors (e.g. ultraviolet radiation, X-rays, gamma rays, etc) and chemical factors (e.g., bromine) can increase this likelihood.

physical and chemical factors

Explanation:

Factors that alter the critical chemical and physical characteristics of ecological systems include temperature, pH electrochemical (redox) potential, and the transparency of air and water.
