A mutation is a permanent, alteration
in genetic material (DNA)
of a cell caused by a change within
the genes or
chromosomes by copying errors
of the genetic material during cell division or by exposure to
radiation, chemicals, or viruses,
this may be accidental or spontaneous, or intentionally induced. |

| A
mutation may cause a plant to have
new character or quality
different from that of the parental type (e.g. new colour of the
flower, or a different shape,
dimension etc..), when such changes occur in the
germ cells, they are able to be
passed on to the offspring as
inherited
traits.
