Sturtevant’s most notable discoveries include the principle of genetic mapping, the first reparable gene defect, the principle of underlying fate mapping, the phenomena of unequal crossing-over, and position effect. His main contributions to science include his analysis of genetic “linkage groups,” which became classical method of chromosome mapping that we still use today.

Griffith’s experiment, reported in 1928 by Frederick Griffith,[1] was the first experiment suggesting that bacteria are capable of transferring genetic information through a process known as
transformation.[2][3] Griffith’s findings were followed by research in the late 1930s and early 40s that isolated DNA as the material that communicated this genetic information.

Sir Francis Galton, FRS (/ˈfrɑːnsɪs ˈɡɔːltən/; 16 February 1822 – 17 January 1911) was an English Victorian statistician, progressive, polymath,sociologist, psychologist,[1][2] anthropologist, eugenicist, tropical explorer, geographer, inventor, meteorologist,
proto-geneticist, andpsychometrician. He was knighted in 1909.. …
He was a pioneer in eugenics, coining the term itself[3] and the phrase “nature versus nurture”.[4] His book Hereditary Genius (1869) was the first social scientific attempt to study genius and
greatness.[5]
…
As the initiator of scientific meteorology, he devised the first weather map, proposed a theory of anticyclones, and was the first to establish a complete record of short-term climatic phenomena on a European scale.[8] He also invented the Galton Whistle for testing differential hearing ability.[9] He was Charles Darwin’s
half-cousin.[10]
