Gregor Mendel used garden pea as experiment model to study the development of plant hybrids. His findings lead to three major conclusions that are coined as the fundamental laws of heredity: the law of dominance, the law of segregation, and the law of independent assortment. However, the significance of his findings has been neglected for 35 years. To explain this puzzle in science history, many efforts have been made by epistemological approaches including the evidence-based historiography and the Kuhnian paradigm-based historiography.

Gregor Mendel, the famous nineteenth-century Austrian botanist, has been considered the discoverer of laws of classical (Mendelian) genetics. Several historians of biology recently began to argue that Mendel had never discovered Mendel’s laws. If he did not discover Mendel’s laws at all, what is his discovery? What is his contribution to science? To answer the above questions, one has to re-examine the whole story of his experimentation and the origin of classical genetics. The philosophical problems involved in scientific discoveries have also to be reconsidered.
