Detailed explanation-1: -A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
Detailed explanation-2: -Plant mutation breeding, also called variation breeding, is a method that uses physical radiation or chemical means to induce spontaneous genetic variation in plants to develop new crop varieties. “Mutation” is the source of most genetic variation and the motor of evolution.
Detailed explanation-3: -Answer & Explanation The statement that is not true regarding mutations is D) Mutations are quite rare. Mutations can occur spontaneously during DNA replication or as a result of exposure to mutagens such as radiation or certain chemicals.
Detailed explanation-4: -A gene variant is a permanent change in the DNA sequence that makes up a gene. This type of genetic change used to be known as a gene mutation, but because changes in DNA do not always cause disease, it is thought that gene variant is a more accurate term.
