Gregor Mendel

Hello  my friends today I will tell you about Gregor Mendel (father of genetics)  was born on 20 July 1822 in a town called Heinzendorf (Czech Republic) at the time was an Austrian province, and was baptized with the name of Johann Mendel, however, took the name of his Father Gregorio when entering as an Augustinian friar, 9 of October of 1843, in the convent of Augustins of Brno and seat of illustrated clergymen. On August 6, 1847, he was ordained a priest. In 1851 he entered the University of Vienna where he studied history, botany, physics, chemistry and mathematics

Mendel began his experiments by choosing two pea plants that differed in one character, crossed a variety that produced yellow seeds with another that produced green seeds; These plants form the so-called parental generation (P).

As a result of this crossing were produced plants that produced nothing more than yellow seeds, repeated the crosses with other pea plants that differed in other characters and the result was the same, a character of the two occurred in the filial generation. To the character that appeared it called dominant character and to which not, recessive character. In this case, the yellow color is one of the dominant characters, while the green color is one of the recessive characters.

The plants obtained from the parent generation are referred to collectively as the first filial generation (F1).

Mendel allowed the first-generation plants to self-fertilize and obtained the so-called second-generation subsidiary (F2), composed of plants producing yellow seeds and plants that produced green seeds in a 3: 1 ratio (three yellow seeds and one Of green seeds). He repeated the experiment with other differentiated characters and obtained similar results in a 3: 1 ratio.

 These experiments were of great help to biology and to humanity since it allowed to understand how the behave the genes and how these can get to express itself throughout the generations.
