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.

54 Parkside the Royal Horticultural Society, of which he was also a Council member. He was appointed a member of the Appeal Tribunal (a special court set up to reconsider a decision by another court) for the County of Berkshire in 1916. One of his friends was William Bateson (1861-1926), an advocate of the ideas of Gregor Mendel who introduced the term ‘genetics’ to describe the study of heredity and whose 1894 book Materials for the Study of Variation was one of the earliest formulations of the new approach to genetics. Sutton provided the means for Bateson to carry out extensive studies
