Question

Role of mutation in crop improvement biology discussion

Answer 1

The credit of discovery of mutation goes to Wright (1791) when he observed it in male sheep. Any permanent or stable hereditary change other than one due to Mendelian segregation and recombination may be termed in its broader sense as mutation. Thus, the term ‘mutation’ in this sense ‘a sudden heritable change in a characteristic of an organism’ was primarily introduced by Hugo de Vries in 1900.

Mutation may be defined as an abrupt or sudden or discontinuous chromosomal change with genetic effect. —Mayer
