Gregor Johann Mendel
Brought to you by Alex Williams and Stephan Dosch
Gregor Mendel, through his work on pea plants,
discovered the fundamental laws of heredity. He understood that genes (or as he
called them: factors) come in pairs and are inherited by offspring as distinct
units, one from each parent. He recognized the mathematical patterns of
inheritance from one generation to the next and from this understood how the two
inherited factors interacted to produce the organism's physical appearance.

de Vries, and Erich von Tschermak-Seysenegg.
Why do you think Mendel's laws went unnoticed
by the scientific community for over one hundred years?
why would a microscope have been helpful to
mendel in his research?
Mendel's Principles can be summarized in three laws:
the Law of Independent Assortment, the Law of Segregation and the Law of
