What is Mutation? Explain Mutation breeding.
@Biplab :- You can refer to the answer given by your friend. However I will like to add some points.
In mutation breeding genetic variations are created, which then result in the creation of traits not found in the parental type. Mutations are induced with the help of mutagens (like chemicals) or irradiation.The plants in which the desired character (in this case, the desired resistance) has come through mutation are selected.
