... Variation exists amongst the members of a species. When a characteristic can be used to divide the species into distinct groups, it is said to show DISCRETE variation. When the characteristic varies in an UNINTERRUPTED way from one extreme to the other, it is said to show CONTINUOUS variation. ...
