  Gregor Mendel - Wikipedia, the free encyclopedia
Gregor Johann Mendel (July 22, 1822 January 6, 1884) was an Austrian monk who is often called the "father of genetics" for his study of the inheritance of traits in pea plants.
Gregor Mendel was inspired by both his professors at university and his colleagues at the monastery to study variation in plants.

 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.

Mendel was interested in the process involved in plant breeding, a millennia-old practice that was until then entirely based on empiricism.
Mendel manually cross-pollinated the varieties to produce several generations of hybrids and observed how the specific traits were transferred from generation to generation.
Mendel's second discovery was that some genes, which he called dominant gametes, suppressed the action of others, which he called recessive gametes The purple-flower gene, for example, is dominant, while the white-flower gene is recessive, which explained why the first generation of hybrids had only purple flowers.

 Gregor Johann Mendel — 1822-1884.
Gregor Johann Mendel, founder of Genetics, was born on 22nd July, 1822, to Anton and Rosine Mendel at the village of Heinzendorf bei Odrau in Austrian Silesia (now in the Czech Republic).
Gregor was an intelligent student at the village school and, at the age of 11, was sent on to Leipnik.

 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.

 Gregor Mendel - Father of Genetics
Mendel was well aware that there were certain preconditions that had to be carefully established before commencing investigations into the inheritance of characteristics.
Mendel's findings allowed other scientists to simplify the emergence of traits to mathematical probability (While mixing one trait always resulted in a 3:1 ratio between dominant and recessive phenotypes, his experiments with two traits showed 9:3:3:1 ratios).
Mendel's ideas on heredity and evolution were diametrically opposed to those of Darwin and his followers (although neither Mendel nor Darwin knew of the other’s work).
