Gregor Mendel , a Moravian Augustinian friar working in the 19th century in Brno , was the first to study genetics scientifically.
Heredity, also called inheritance or biological inheritance, is the passing on of traits from parents to their offspring; either through asexual reproduction or sexual reproduction, the offspring cells or organisms acquire the genetic information of their parents.

A geneticist is a biologist or physician who studies genetics, the science of genes, heredity, and variation of organisms. [1] A geneticist can be employed as a scientist or a lecturer. Geneticists may perform general research on genetic processes or develop genetic technologies to aid in the pharmaceutical or and agriculture industries. [1]
Twenty years later, in 1909, Wilhelm Johannsen introduced the term "gene" (inspired by the ancient Greek: γόνος, gonos, meaning offspring and procreation) [36] and, in 1906, William Bateson, that of "genetics" [37] [29] while Eduard Strasburger, among others, still used the term "pangene" for the fundamental physical and functional unit of ...
Special attention has been paid to users who are learning or teaching genetics in the classroom. However, the Glossary is designed to be valuable for a much wider audience including patients, doctors, nurses, parents, and professionals dealing with genetic concepts and terminology, such as judges, lawyers, law enforcement officials, and others.
