  Gregor Mendel
Gregor Johann MENDEL was an Austrian monk and biologist whose work on heredity became the basis of the modern theory of genetics.
Between 1856 and 1863 Mendel patiently cultivated and tested at least 28 000 pea plants, carefully analysing seven pairs of seeds for comparison, such as shape of seed, colour of seed, tall stemmed and short stemmed and tall plants and short plants.
Mendel successfully produced a hybrid strain of bees which produced excellent honey, however, they were so vicious they stung everybody around for miles and had to be destroyed.

 Gregor Mendel (1822-1884)
Mendel, the first person to trace the characteristics of successive generations of a living thing, was not a world-renowned scientist of his day.
Mendel's brilliant performance at school as a youngster encouraged his family to support his pursuit of a higher education, but their resources were limited, so Mendel entered an Augustinian monastery, continuing his education and starting his teaching career.
From his studies, Mendel derived certain basic laws of heredity: hereditary factors do not combine, but are passed intact; each member of the parental generation transmits only half of its hereditary factors to each offspring (with certain factors "dominant" over others); and different offspring of the same parents receive different sets of hereditary factors.

 Mendel, Gregor Johann. The Columbia Encyclopedia, Sixth Edition. 2001-05
Mendel was the first to fashion, by means of a controlled pollination technique and careful statistical analysis of his results, a clear, analytic picture of heredity.
Briefly summarized, as we understand it today by means of the science of genetics, the Mendelian system states that an inherited characteristic is determined by the combination of a pair of hereditary units, or genes, one from each of the parental reproductive cells, or gametes.
The law of segregation (Mendel’s first law) states that in the process of the formation of the gametes (see meiosis) the pairs separate, one going to each gamete, and that each gene remains completely uninfluenced by the other.
