What was the most significant conclusion that gregor mendel drew from his experiments with pea plants?

Important conclusions form Mendelian experiments are:

• The inheritance of each trait is determined by "units" or "factors" (we call it genes today) that are passed on offspring unchanged

• An individual inherits one unit from mother and another from father (for each trait)

• A trait may not show up in an individual but can still be passed on to the next generation (allele).
