This article will reveal the interesting 10 facts about Mendelian genetics. I will focus on the Mendelian inheritance. It is a type of biological inheritance that follow the laws originally raised by Gregor Mendel in 1865 and 1866 and discovered in 1900. He became the classical genetics after integrated with the Boveri-Sutton chromosome theory of inheritance by Thomas Hunt Morgan in 1915. You could find the others facts about Mendelian genetics in the pieces of the description below.

Facts about Mendelian Genetics 1: The History of Mendelian Genetics

In the 19th century, Moravian monk which is Gregor Johann Mendel formulated his ideas after conducting simple hybridisation experiments with pea plants (Pisum Sativum) he had planted in the garden of his monastery. Then Gregor Johann Mendel became the principles of Mendelian inheritance.

Facts about Mendelian Genetics 2: Initial Mendel’s Conclusions

Mendel’s conclusions were largely ignored by the vast majority. Even though they were not completely unknown to biologist of the time, they were not seen as generally applicable, even by Mendel himself, who thought they only applied to certain categories of species or traits.

Facts about Mendelian Genetics 3: Re-discovered of Mendel invention

in 1900, the three European scientists, Hugo de Vries, Carl Correns and Erich von Tschermak tended to “re-discovered” Mendel’s discovery. Regardless, the re-discovery made Mendelism an important but controversial theory. William Bateson was the most vigorous mendelian promotor in Europe.

Facts about Mendelian Genetics 4: The First Mendel’s Laws

There are three Mendel’s laws of inheritance namely law of segregation, law of independent assortment and law of dominance. The first one is law of segregation, it is stated that during gamete formation, the alleles for each gene segregate from each other so that each gamete carries only one allele for each gene.

Facts about Mendelian Genetics 5: The Second Mendel’s Laws

The second Mendel’s laws named law of independent assortment. It is said that genes for different traits can segregate independently during the formation of gametes.

Facts about Mendelian Genetics 6: The Third Mendel’s Laws

Law of dominance is the third mendel’s law. It was claimed that some alleles are dominant while others are recessive; an organism with at least one dominant allele will display the effect of the dominant allele.

Facts about Mendelian Genetics 7: Mendelian Trait

Single locus inheritance pattern controls a Mendelian trait. In such conditions, a mutation in a single gene can cause a disease that is inherited according to Mendel’s laws. For instance, include sickle-cell anemia, Tay-sachs disease, cystic fibrosis and xeroderma pigmentosa.

Facts about Mendelian Genetics 8: The Disease that Appeared due to Mutation in a Single Gene

A disease controlled by a single gene with a multi-factorial disease, such as arthritis, which affected by several loci (and the environment) as well as those diseases inherited in a non-mendelian fashion.

Facts about Mendelian Genetics 9: Non-Mendelian Inheritance

Mendel stated inheritance in term of discrete factors – gene – that are passed along from generation to generation according to the rules of probability. Mendel’s laws are valid for all sexually reproducing organisms, including garden peas and human being.

Facts about Mendelian Genetics 10: The Pattern of Genetic Inheritance

For most sexually reproducing organisms, cases, where Mendel’s laws can strictly account for the patterns of inheritance, are relatively rare. Often, the inheritance patterns are more complex.
