It can hardly be said that Mendel had been a proponent, even less the first proponent, of Genetics. He was actually an excellent "hybridist". His hybridism consists of two theories: a first theory that moves on a level more "empirical" or "phenomenological" (according to Schleiden 1849: 141-146), which can be called "Mendel's theory of the development/evolution of hybrids" (DEH), and a second theory that moves on a level more "theoretical" (according to Schleiden 1849: 146-148), which can be called "Mendel's theory on the cellular foundation of the development/evolution of hybrids" (CFH).The aim of this communication is to present an analysis of these two theories and of their intertheoretical relationships, carried out within the framework of the so-called Metatheoretical Structuralism.
