Mutations can be induced with
IAA
ethylene
gamma radiations
infrared radiations
Mutations can be induced by a variety of factors such as radiation, chemicals, and transposable elements. Gamma radiation is a type of ionizing radiation that can induce mutations by breaking the DNA strands. It is commonly used in mutation breeding programs to create genetic variability in crops for the development of improved varieties with desirable traits. IAA (indole-3-acetic acid) and ethylene are plant growth regulators and do not induce mutations directly. Infrared radiation does not have enough energy to cause ionization of atoms and molecules and thus cannot induce mutations.
Option 3 is the correct answer.
