Gregor Mendel

The Austrian Who Took Genetics to the Next Level

Who is Mendel?

Gregor Mendel was an Austrian monk that focused most of his time on genetics and how people inherited traits.

Early Years

Mendel grew up a gifted child. He scored high on math and science tests. On the down side, while Mendel was in school he had troubles because he had to speak two different languages between school and home. As Mendel moved onto college, he had trouble taking very important tests.


Dominant: A dominant gene is when there is one gene that will overpower the rest. For example, this website says that long eyelashes are a dominant gene.

Recessive: A recessive gene is a gene that doesn't appear very often. For example, an attached earlobe is a recessive trait.

Codominant: A codominant gene is when a gene is neither dominant or recessive. For example, a husky can have a brown and blue eye, which makes them codominant traits.

Pea Plants

Mendel used pea plants to further understand genetics. He started his study with 1 yellow and 1 green pea plant. He cross breed the plants and further focused on heredity. The first set of pea plants, the offspring were all yellow. When he breed the new yellow plants, 3/4 of the plants were yellow, but the rest were green.

Mendel's Data

When Mendel did his experiment with the pea plants, he used yellow and green peas. When he cross-breed the plants, he got 3 yellow plants for every 1 green plant. He found out that some traits are more dominant than others.

Other Reactions

Mendel had written an article about his discoveries. At the time of his findings, not many other scientist were interested in genetics because they didn't understand it like Mendel did. Genetics weren't studied until many years later when a few other scientist stumbled across his article.

Genetic Discoveries

After Mendel's discovery, many improvements took place in the genetic field to further the understanding of genetics. 'Cloning' was a genetic advancement in the genetic community. None of this would have been possible if Mendel wouldn't have noticed how organisms inherits traits.
