The man who first came to see and to really grasp this important phenomenon was Gregor Johann Mendel (1822 – 1884), who began his research around 1856 starting with experiments on phenotypic phenomena that occurred in sets of pairs contrary to each other in appearance, either in size, form or colour as phenotypic accessories of a one and the same species. This way than he could ‘discover’ and proof that genetic information exists, and exists as discrete units occurring in pairs; the practical basic condition for the possibility of combination or of the pathway along which combination regarding life can make sense as we came to understand again and again later on.
