Differences within individuals
of the same species are called variations.
Variation can also be defined as ‘
Morphological or physiological changes
in an organism either due to genetic or environmental factors’.
Variation is a common phenomenon observed in all the living organisms.
Some of these variations may be
favourable
thereby increasing the chances for survival.
Others may be
neutral or harmful.
It is a
pre-requisite
and
progressive factor
in
evolution.
