Mendel's Original Paper

The paper that established the foundations of modern genetics, but was neglected for 34 years.

Mendel rediscovered by de Vries, Correns, and von Tschermak

In 1900, several researchers rediscovered Mendel's work.

William Bateson promotes Mendelism

Bateson was one of the first to recognize the truly transformative nature of Mendel's approach.

Thomas Morgan discovers first X-linked gene in Drosophila

The discovery of an X-linked gene provided Morgan and his group with the starting point for establishing the chromosomal model of inheritance.

Alfred Sturtevant creates the world's first genetic map

Sturtevant (one of Morgan's students) created the first chromosomal map while he was still an undergraduate.

Calvin Bridges provides proof that sex-linked genes are physically carried on the X chromosome

Bridges (another of Morgan's students) carried out work that proved that genes were carried on chromosomes.

Hermann Muller studies the mechanism of crossing-over

Muller (another of Morgan's students) made a systematic study of crossing-over - the process by which genetic material is exchanged between chromosomes.

T. H. Morgan and his students (Sturtevant, Bridges, and Muller) publish a monograph on The Mechanism of Mendelian Heredity

In 1915, Morgan and his students publish a monograph describing their model for the mechanisms of Mendelian heredity.

Originally published in 1965, this book was jointly republished in 2001 by the Cold Spring Harbor Laboratory Press and the Electronic Scholarly Publishing Project. This is one of the few histories of early genetics written by one who was there. Although originally neglected because it appeared concurrently with the sudden rise of molecular genetics, it is still essential reading for anyone interested in the history of genetics.
