Mutations are changes in a genomic sequence that can occur randomly or be induced. They are caused by factors like radiation, viruses, chemicals, and errors during cell replication or meiosis. Mutations can be classified as genomatic, chromosomal, or gene mutations. Mutation causes changes in the chemical composition and morphology of plants. For example, the solasodine content in solanum khasianum was increased by both radiation and chemical mutagens, while the diosgenin content and tuber yield in dioscorea was reduced by radiation mutagens. Mutations induced in poppy seeds with carbon-14 radiation produced a number of mutations.
