Modern genetics started with Mendel’s studies of the nature of inheritance in plants. In his paper “Versuche über Pflanzenhybriden” (“Experiments on Plant Hybridization“), presented in 1865 to the Naturforschender Verein (Society for Research in Nature) in Brünn, Mendel traced the inheritance patterns of certain traits in pea plants and described them mathematically.[14] Although this pattern of inheritance could only be observed for a few traits, Mendel’s work suggested that heredity was particulate, not acquired, and that the inheritance patterns of many traits could be explained through simple rules and ratios.
The importance of Mendel’s work did not gain wide understanding until 1900, after his death, when Hugo de Vries and other scientists rediscovered his research.William Bateson, a proponent of Mendel’s work, coined the word genetics in 1905(the adjective genetic, derived from the Greek word genesis—γένεσις, “origin”, predates the noun and was first used in a biological sense in 1860). Bateson both acted as a mentor and was aided significantly by the work of other scientists from Newnham College at Cambridge, specifically the work of Becky Saunders, Nora Darwin Barlow, and Muriel Wheldale Onslow.Bateson popularized the usage of the word genetics to describe the study of inheritance in his inaugural address to the Third International Conference on Plant Hybridization in London in 1906.
After the rediscovery of Mendel’s work, scientists tried to determine which molecules in the cell were responsible for inheritance. In 1911, Thomas Hunt Morgan argued that genes are on chromosomes, based on observations of a sex-linkedwhite eye mutation in fruit flies.In 1913, his student Alfred Sturtevant used the phenomenon of genetic linkage to show that genes are arranged linearly on the chromosome.
