Mendel published his important work on heredity in 1866. Despite, or perhaps because of, its descriptions of large numbers of experimental plants, which allowed him to express his results numerically and subject them to statistical analysis, this work made virtually no impression for the next 34 years.
Only in 1900 was his work recognized more or less independently by three investigators, one of whom was the Dutch botanist Hugo Marie de Vries, and not until the late 1920s and the early 30s was its full significance realized, particularly in relation to evolutionary theory.
As a result of years of research in population genetics, investigators were able to demonstrate that Darwinian evolution can be described in terms of the change in gene frequency of Mendelian pairs of characteristics in a population over successive generations.
Mendels later experiments with the hawkweed Hieracium proved inconclusive, and because of the pressure of other duties he ceased his experiments on heredity by the 1870s. He died in Brnn on January 6, 1884.
