All mutations observed are due to wild crossing most especially to the action of TRANSPOSONS.
Barbara McClintock - Nobel prize in 1983 discovered transposons.
About 50% of the total genome of maize concists of transposons.

Transposon = jumping genes.
mobile genetic elements vector of mutations .
"Junk DNA"

They can be inserted at another position in the genome - technic of "Cut and Paste"
The process can cause mutations.

Since excessive transposon activity can destroy a genome , many organisms seen to have developed mechanisms to reduce transposition to a manageable level .
