Hardy-Weinberg conditions.
<P>
   Mendelian inheritance preserves allele frequencies from one generation
   to the next.
   This  incomplete dominance of flower color gene preserves the ratio of
   C^R and C^W alleles between generations.
   Over  time,  the  allele frequencies reach Hardy-Weinberg equilibrium,
   assuming five idealized conditions:
<P>
<BR><LI> Extremely large population size.
<BR><LI> No gene flow due to migration.
<BR><LI> No mutations.
<BR><LI> Random mating.
<BR><LI> No natural selection.
