Douglas Scott Falconer (10 March 1913 in Oldmeldrum, Aberdeenshire – 23 February 2004 in Edinburgh) was a Scottish geneticist known for his work in quantitative genetics.
Falconer's book Introduction to quantitative genetics was written in 1960 and became a valuable reference for generations of scientists.
Its latest edition dates back to 1996 and is coauthored by Trudy Mackay.In 1951, Falconer described a novel mouse mutant that he called reeler for its peculiar gait.
Later research using these mice has led to the discovery of reelin, a protein playing important roles in corticogenesis, neuronal migration, and plasticity.
In 1964, he introduced the use of liability threshold models into human disease & trait modeling.In 1973, he was announced as a Fellow of the Royal Society (FRS).
