Gregor Mendel and Genetic Behavior

Mendel's 1865 paper "Experiments in Plant Hybridization" is an account of a systematic project in which the researcher seeks to explain whether, how, and to what extent it is possible to identify and manipulate principal characteristics of interbred pea plants down the generations. It is clear from Mendel's report that he understood that making this determination would involve an ability to recognize what the principal characteristics of the plants are in the parent organisms. Once such characteristics are identified in parent plants in which certain characteristics are different, they can be recognized in hybrid plants that emerge as a consequence of artificial interbreeding of parent plants.

The hypothesis that Mendel articulates brings these assumptions to bear on his method. The fundamental hypothesis is that "the number of different forms under which the offspring of the hybrids appear" can be determined or "arranged," i.e., manipulated (Mendel 1). The idea is to "discover the relations in which the

cteristic only, then breeding the offspring of these plants to produce a second generation. When the second-generation characteristics emerged, how the traits were inherited could be identified. Thus cross breeding of plants proceeded based on the differences in one of the seven traits only. Equal numbers of plants of the same kind functioned as seed pollinators (male) and as receivers of pollen (female). Thus for example, pollen from one long-stemmed plant would be deposited in the egg of one short-stemmed plant, and pollen from a short-stemmed plant would be deposited in the egg of a long-stemmed one. It was determined immediately that the form a hybrid assumed remained identical in both cases (Mendel 3). What the hybrid progeny revealed was how the traits combined to reveal whether they were dominant or and recessive. Short-stemmed plants that received tall-stem pollen yielded tall-stemmed offspring. But if that tall generation pollinated naturally, the next offspring plants came out in a ratio of 3:1, tall to short. [T]hose characers which are transmitted entire, or almost unchanged in the hybridization, and therefore in themselves constitute the characters of the hybrid, are termed the dominant, and those which become laten
