The renowned scientist credited with significant advancements in the field of genetics is Gregory Mendel. Often referred to as the "father of genetics," Mendel conducted pioneering experiments with pea plants in the mid-19th century, establishing the foundational principles of inheritance. His work identified concepts such as dominant and recessive traits, and the laws of segregation and independent assortment, though his work went largely unrecognized during his lifetime. Mendel's discoveries laid the groundwork for modern genetics, influencing the study of heredity and the biological sciences, ultimately shaping our understanding of variation and evolution.
