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.
@ Vineeta :- Good work, keep contributing !!
Mutation is an accidental change in an organism’s gene or chromosome that results in a new trait. This trait can be passed on to the organism’s offspring. Mutation can be either beneficial or harmful. If it is beneficial, it may result in a new adaptation that may allow the organism to better survive in its environment.
Mutation breeding is the process of exposing seeds to chemicals or radiations in order to generate mutants with desirable traits to be bred with other cultivators. Plants created using mutagenesis are sometimes called mutagenic plants or mutagenic seeds.
