Through advances in science it is now possible to
identify race based on genetic markers such as
blood groups.  

Due to the easily identifiable differences in the
appearance of members of a particular race,
members of each race share some common
experiences shaping their culture.

Although the genetic differences between races is
minimal, just one letter out of the 3.1 billion letters in
the genetic code, people within develop cultures.
