     In a paper presented to the Royal Institute on February 9, 1877,
     Sir Francis Galton discussed his experiments on sweet peas in
     which he compared the sweet peas produced by parent plants to
     those produced by offspring plants. In these experiments he could
     observe inheritance from one generation to the next. Galton
     categorized the parent plants according to the typical diameter of
     the peas they produced.
