The famous scientist known for his contributions to the field of genetics is Gregor Mendel. An Austrian monk, Mendel conducted groundbreaking experiments with pea plants in the mid-19th century, laying the foundation for classical genetics. Through his observations of heredity, Mendel formulated the basic laws of inheritance, including concepts like dominant and recessive traits. His meticulous cross-breeding experiments allowed him to deduce how traits are passed from one generation to the next. Although initially overlooked, Mendel's work gained recognition in the early 20th century, establishing him as the "father of genetics" and enormous influence on biology and the understanding of heredity.
