Classical genetics genetics is often referred to as the oldest form of genetics, and began with Gregor Mendel's experiments that formulated and defined a fundamental biological concept known as Mendelian Inheritance. Mendelian Inheritance is the process in which genes and traits are passed from a set of parents to their offspring. These inherited traits are passed down mechanistically with one gene from one parent and the second gene from another parent in sexually reproducing organisms. This creates the pair of genes in diploid organisms. Gregor Mendel started his experimentation and study of inheritance with phenotypes of garden peas and continued the experiments
Gregor Mendel the Moravian-Silesian border, Austrian Empire (now a part of the Czech Republic). He was the son of Anton and Rosine (Schwirtlich) Mendel and had one older sister, Veronika, and one younger, Theresia. They lived and worked on a farm which had been owned by the Mendel family for at least 130 years (the house where Mendel was born is now a museum devoted to Mendel). During his childhood, Mendel worked as a gardener and studied beekeeping. As a young man, he attended gymnasium in Opava (called "Troppau" in German). He had to take four months off during his gymnasium studies
