Known as the Father of Genetics: His experiments with Pea plants from 1856-1863 began our understanding of how traits, things like hair or eye color, height, weight, ect……., were passed down from generation to generation.
He came up with the principles of heredity that still hold true today by studying 7 characteristics of peas in his garden.
His work started and formed the base of all genetics, a field we learn more about every day.
