 Why is it that you and your siblings look similar?  Why do you look like your parents?  How does heredity work?  Why do we have our father's blue eyes or our mother's red hair?  All our traits are determined by DNA.  But it wasn't until 1856 that Gregor Mendel unlocked the secrets of heredity.  Come along and find out how his observations of pea plants was the beginning of the amazing discovery of the structure of DNA.
