Happy birthday to you, happy birthday to you, happy birthday dear Mendel…

July 22 marks the 200th birthday of Gregor Mendel. Although an Austrian monk, he won lasting scientific fame as the biologist who bred pea plants in his garden — and along the way discovered the rules of heredity. This week, celebrate the father of genetics by learning about his foundational experiments and what we know about genes today. For the story of how we got from Mendel to modern genetics, check out Science News’ Century of Science piece “The Human Blueprint” and a Q&A with philosopher of science Yafeng Shan.
