Mendel and modern genetics: the legacy for today

The legacy of Mendel's pioneering studies of hybridization in the pea continues to influence the way we understand modern genetics. But what sort of picture did Mendel himself have of his work and its ultimate uses, and how does that picture compare with the collection of ideas and methodologies that was put forward in his name and later became known as 'Mendelism'? With genetics standing at the center of our present biomedical and biotechnological research, an examination of the history of our concepts in the field can help us better understand what we should and should not expect from current genetic claims. For that enterprise there is no better starting place than Mendel himself.
