Forward genetics a bare minimum for the appearance of specific phenotypes. However, such initial screens were either incomplete as they were missing redundant loci and epigenetic effects, and such screens were difficult to undertake for certain phenotypes that lack directly measurable phenotypes. Additionally a classical genetics approach takes significantly longer. Gregor Mendel experimented with pea plant phenotypes and published his conclusions about genes and inheritance in 1865. Around the early 1900s Thomas Hunt Morgan was mutating Drosophila using radium and attempting to find heritable mutations Alfred Sturtevant later began mapping genes of Drosophila with mutations they had been following. In the 1990s
Mount Mendel Mount Mendel Mount Mendel is a peak in Fresno County, California. It is in Kings Canyon National Park in the Evolution Region, of the Sierra Nevada and adjacent to Mount Darwin which is on the Sierra crest. Theodore S. Solomons and E. C. Bonner of the United States Geological Survey named a series of mountains for the six major exponents of the theory of evolution. Mount Mendel is named for, Gregor Mendel, an Augustinian friar, who is known as the "father of modern genetics". Other nearby mountains in the group include Mount Darwin, Mount Fiske, Mount Haeckel, Mount Huxley, Mount
