Mendal life and times

Gregor Johann Mendel (July 20, 1822 – January 6, 1884) was an Augustinian priest and scientist, who gained posthumous fame as the figurehead of the new science of genetics for his study of the inheritance of certain traits in pea  plants. Mendel showed that the inheritance of these traits follows particular laws, which were later named after him. The significance of Mendel's work was not recognized until the turn of the 20th century. The independent rediscovery of these laws formed the foundation of the modern science of genetics.  Gregor Mendel, who is known as the "father of modern genetics", was inspired by both his professors at university and his colleagues at the monastery to study variation in plants

-Born- July 20, 1822

-Died- January 6, 1884 (chronic nephritis)


This will link you to a website that gives a general overview of Mendel's life an accomplishments in the field of heredity. It is an entry in the Columbia Encyclopedia




-In general famous for discovering genetics. He worked with various pea plants and studied the flower color, placement, pea pod shape, and other characteristics.

-Mendal figured out that there are dominate and recessive phenotype. He also discovered that if two tall pea plants are cross pollenated, the outcome maybe a short pea plant. 

This picture does a very good job illustrating what Mendel was doing. He found that trait were passed down through the generations, just like the short gene was passed down from the grand mother plant to the grand daughter plant.


this video does a good job of summing up what Mendal did in a nut shell.

Mendel, who is known as the "father of modern genetics", was inspired by both his professors at university and his colleagues at the monastery to study variation in plants, and he conducted his study in the monastery's garden. Between 1856 and 1863 Mendel cultivated and tested some 29,000 pea plants (i.e., Pisum sativum). This study showed that one in four pea plants had purebred recessive alleles, two out of four were hybrid and one out of four were purebred dominant. His experiments brought forth two generalizations, the Law of Segregation and the Law of Independent Assortment, which later became known as Mendel's Laws of Inheritance. 


Before Mendel did his famous work with pea plants, he worked with mice. Mice are common test subjects due to their relatively quick breeding and fertilazation period. By using mice, mendel could get perhaps 12 generations within one year, whereas peas were perennial and took one year for each generation. 


After Mendel completed his work with peas, he turned to experimenting with honeybees, in order to extend his work to animals. He produced a hybrid strain (so vicious they were destroyed), but failed to generate a clear picture of their heredity because of the difficulties in controlling mating behaviours of queen bees. He also described novel plant species, and these are denoted with the botanical author abbreviation "Mendel".


It was not until the early 20th century that the importance of his ideas was realized. By 1900, research aimed at finding a successful theory of discontinuous inheritance rather than blending inheritance led to independent duplication of his work by Hugo de VCries and Carl Correns, and the rediscovery of Mendel's writings and laws. Both acknowledged Mendel's priority, and it is thought probable that de Vries did not understand the results he had found until after reading Mendel. Though Erich von Tschermak was originally also credited with rediscovery, this is no longer accepted because he did not understand Mendel's laws. Though de Vries later lost interest in Mendelism, other biogists started to establish genetics as a science.


Mendel's work revisited looks something like this:


Dominant and recessive phenotypes. (1) Parental generation. (2) F1 generation. (3) F2 generation.

this video talks about what Mendal did in a creative way.


This is just a pretty simple video of Gregor Mendel and his discoveries

This is a picture of a punnett square, which has to do with genetics.




^^^ this video gives a brief bio on Mendal however after a little bit it gets into his discoveries and laws.


This video is a rap about meiosis and how Gregor Mendal discovered it with his flower experiments.  It goes over Mendal's life and how he developed his findings on inheritance.  Honestly this is the only way I can remember that meiosis makes gametes. YouTube plugin error



Here's a helpful link that goes into a lot of depth describing mendel and his work in the field of genetics: http://www.ndsu.edu/pubweb/~mcclean/plsc431/mendel/mendel1.htm
