The garden pea has closed flowers
   and can self-fertilize, but also allow for manual cross-pollination.
<P>
   Mendel  studied  inheritance  of a single character (or trait, such as
   flower  color) by cross-pollinating two true-breeding varieties of the
   pea.
<P>
<bR>This is called a monohybrid cross.
   When  pollen  from  a white flower fertilizes eggs of a purple flower,
   the first-generation hybrids (F[1]) all have purple flowers.
