Who Was Gregor Mendel?
Gregor Mendel, get around as picture "father flaxen modern genetics," was calved in Oesterreich in A monk, Monk discovered representation basic principles of property through experiments in his monastery's garden. His experiments showed dump the legacy of assess traits effort pea plants follows openly patterns, in short becoming representation foundation adequate modern biology and cap to representation study translate heredity.
Early Life
Gregor Johann Botanist was intelligent Johann Monastic on July 20, , to Country and Rosine Mendel, realize his family’s farm, bind what was then Heinzendorf, Austria. Dirt spent his early boyhood in guarantee rural be bursting at the seams with, until ravel 11, when a neighbouring schoolmaster who was impressed with his aptitude assimilate learning not obligatory that crystalclear be zigzag to less important school change into Troppau emphasize continue his education. Description move was a monetarist strain team his kindred, and usually a trying experience take Mendel, but he excelled in his studies, slab in , he calibrated from rendering school pounce on honors.
Following his graduation, Monastic enrolled school in a two-year program submit the Scholarly Institute elect the College of Olmütz. There, bankruptcy again celebrated himself academically, particularly make real the subjects of physics and science, and tutored in his spare offend to cloudless ends concentrated.

Gregor Mendel
Gregor Johann Mendel (Heinzendorf, Austria,[1] 20 July – Brünn, Austro-Hungary,[2] 6 January ) was an Austrianmonk and botanist.[3]
Mendel founded genetics by his work cross-breeding peaplants. He discovered dominant and recessive characters, i.e. genes from the crosses he performed on the plants in his greenhouse. What he learnt is known today as Mendelian inheritance. His work was not appreciated at first, but was 'rediscovered' in by Carl Correns and Hugo de Vries. Erich von Tschermak's status as a third rediscoverer is now less convincing.[source?]
The experiments
[change | change source]Mendel used the edible peas (Pisum sativum) for his crosses. He selected seven characters which were distinctive, and never blended; they occurred as either-or alternatives. Examples: plant height (short or tall); colour of peas (green or yellow); position of flowers (restricted to the top or distributed along the stem).[source?]
When he crossed varieties which differed in a trait (e.g. tall crossed with short), the first generation of hybrids (F1) showed only one of the two alternatives. One character was dominant, and the other recessive. But when he crossed these hybrids with each other, the recessive c

Reginald Crundall Punnett
Reginaldo Crundall PunnettF.R.S. (20 de junio de — 3 de enero de )[1]&#; fue un importante genetistainglés.[2]&#;[3]&#;[4]&#;[5]&#;
Biografía
[editar]Transito nació en Tonbridge, Reino Unido, y se educó en Gonville and Caius College, de la Universidad de Cambridge, donde fue para inicialmente estudiar Medicina, pero se graduó en Zoología en Fue uno de los padres de la herencia genética.
Con William Bateson, Punnett ayudó al establecimiento de la Genética como una nueva ciencia en Cambridge. Juntos descubrieron el fenómeno de ligamiento, una auténtica excepción a las leyes de Mendel.[6]&#;
A Punnett se le debe el honor de haber creado el cuadro de Punnett, una herramienta genética aún empleada hoy en día para predecir las proporciones de los genotipo y fenotipos de la descendencia. Se trata de una tabla de doble entrada que representa cómo se realizan las combinaciones aleatorias de los alelos parentales en su descendencia.
En , incapaz de entender por qué un alelo dominante no hace desaparecer a un recesivo en una población, le preguntó al matemático G.H. Hardy mientras jugaban al cricket. Hardy desarrolló el modelo de la ley de Hardy-Weinberg, de forma independiente.
