Degree of genetic variation (cont.)

• When there is a great genetic difference
between the members of a certain
genus……… (different species)

• we find morphological, histological and
biochemical differences between these
members or these species.

• But when the genetic difference is little or
small, biochemical variation occurs only
without any morphological or histological
differences.
