The Laws of Heredity
Today is the birthday of the Austrian botanist and monk Gregor Mendel.
Gregor discovered the basic principles of heredity through his experiments with peas in his garden at the Augustinian monastery that he lived in at Brno ("BURR-no") in the Czech Republic.
Or, as I like to tell the kids, Gregor learned about heredity when he gave peas a chance. (Sorry, couldn't resist!)
During seven years in the mid-1800s, Gregor grew nearly 30,000 pea plants, and he took note of everything: their height and shape and color. And, his work resulted in what we now know as the Laws of Heredity, and to this day, most kids study this in school. And it was Gregor who came up with all of the genetic terms and terminology that we still use today, like dominant and recessive genes.
