On July 22, 1822, Mendel was born.

Mendel, the founder of modern genetics, was born in Austria.

In the mid-19th century, as a biology teacher, in order to explore the secrets of plant growth, he conducted "plant hybridization" experiments on campus, and for the first time proposed the concept of genetic units (now called "genes"), establishing genetics

Based on mathematics, it was later called Mendel's laws and Mendelism.

Practice has proved that this theory has a profound impact not only on genetics, but also on biology as a whole. It is one of the basic theories of biology.

Mendel died on January 6, 1884.
