What was the most significant conclusion that Gregor Mendel drew from his experiments with pea plants?
(1) There is considerable genetic variation in garden peas.
(2) Traits are inherited in discrete units, and are not the results of ʺblending.ʺ
(3) Genes are composed of DNA.
(4) An organism that is homozygous for many recessive traits is at a disadvantage.
