Detailed explanation-1: -By experimenting with pea plant breeding, Mendel developed three principles of inheritance that described the transmission of genetic traits, before anyone knew genes existed. Mendel’s insight greatly expanded the understanding of genetic inheritance, and led to the development of new experimental methods.

Detailed explanation-2: -Three botanists-Hugo DeVries, Carl Correns and Erich von Tschermak-independently rediscovered Mendel’s work in the same year, a generation after Mendel published his papers. They helped expand awareness of the Mendelian laws of inheritance in the scientific world.

Detailed explanation-3: -As the father of modern genetics, Gregor Mendel is considered one of these giants owing to his discovery of the basic principles of inheritance.
