WHO WAS GREGOR MENDEL?

Gregor Johann Mendel

Gregor Johann Mendel (20 July 1822 to 6 January 1884).
He was an Austrian biologist with different varieties of peas deduced the basis of genetic inheritance today.

After a childhood marked by poverty, Johann Gregor Mendel in 1843 became part of an Augustinian monastery Königskloster order which was named abbot in 1868.

Initially made ​​in the garden of the monastery, crosses with varieties of peas (Pisum sativum) and it was noticed that the results were predictable in terms of proportions and probabilities, but at the time was unaware of the existence of genes and also were not taken into account at the end of his studies until a few years later.

The three laws discovered by Mendel were:

· First, when crossed two varieties of the same pure species , descendants are all the same and can resemble either parent or any of them.

· A second states that cross each other in the hybrids of the second generation, the descendants are divided into four parts, one of which resembles her grandmother, another to his grandfather and the other two to his parents.

· The third law concludes that, if the two varieties differ in starting two or more characters, each of which is transmitted in accordance with the first law, regardless of others.

His work was not valued when published in 1866. Hugo de Vries, Dutch botanist Carl von Corrns and Enrich Tschermark separately rediscovered Mendel's laws in 1900.
