Gregor Mendel is often considered the founder of contemporary genetics. Farmers knew that crossings of animals and plants may be beneficial for desirable features over centuries, but the Mendel pea plant experiments conducted between 1856 and 1863 were more numerous Established genetic rules.

Now living in the Russian monk of the Czech Republic, Mendel can enter the experimental garden, where he breeds the real series of pea plants and patiently crosses them in a certain combination patiently Wait for. He studied seven characteristics of pea plants: plant height, shape and color of pod, seed shape and color, flower position and color. Using the seed color example, his results show that when the yellow peas and the green peas grow together, their descendants plants are always yellow. However, in next generation plants, green peas will reappear at a ratio of 1: 3.

To illustrate this phenomenon, Mendel referred to recessive and dominant terms while referring to specific features. (In the previous example, Greenpeace was recessive and Yellowpiece was dominant.) He published his research in 1866 and showed a role of intangible 'factor'. Prediction method to provide visible features

Mendel has never enjoyed recognition in his life. In fact, in 1900, more than 30 years ago, three scientists engaged in agricultural research discovered his 1866 paper. Erich Tschermak, Hugo de Vries, Carl Correns independently verified some of Mendel's experimental results, "Genetics Age" was born. Over the next few decades, scientists will learn more about genes and special substances called DNA, which have specific characteristics of each organism.

DNA research is just one way to analyze population biology. There are several good sources in the population history section of this paper, and its organizational structure is not as good as most parts. AncientObserver (talk) I noticed that I am about to hijack this article to "prove" that AE is black on 17th April 2009, 09: 20 (UTC). In this attempt, material that destroyed POV was not directly attributable to material that was inappropriate weighted for "controversial" or "controversial" material, or where "controversial" material was not directly related to the subject Has been deleted. .

As part of history, Africa It should be a part of the controversy about the association between "Today's Consensus" and "modern academics." The observational observation of the sphinx data should go back a while. "Definition of the race" Science of the race It covers scientific consensus and covers scientific consensus "Race and Science" also applies to ancient Egypt, so in order to cover the scientific and social aspects of "race and science" this section You can incorporate it.
