Gregor Mendel is known as the Father of Modern Genetics. He is a pretty big name in the science world. However, he did not receive any of this credit while he was alive. We'll come back to this later. Mendel was born in Austria in 1822. His parents were farmers. When he was young and on the farm, Mendel became very interested in plants, trees, and fruit.
He then conceived the idea of heredity units, which he called factors. Mendel found that there are alternative forms of factorsânow called genesâthat account for variations in inherited characteristics. For example, the gene for flower color in pea plants exists in two forms, one for purple and the other for white. The alternative forms are now calledalleles.
