===Experiments on twins===
Experiments on twin children in concentration camps were created to show the superiority of heredity over the environment in determining phenotypes and to find ways to increase German reproduction rates. The central leader of the experiments was Josef Mengele, who from 1943 to 1944 performed experiments on nearly 1,500 sets of imprisoned twins at Auschwitz. About 200 people survived these studies.<ref>[http://www.longwood.k12.ny.us/lhs/science/mos/twins/mengele.html Josef Mengele and Experimentation on Human Twins at Auschwitz] {{webarchive|url=https://web.archive.org/web/20150414074936/http://www.longwood.k12.ny.us/lhs/science/mos/twins/mengele.html |date=14 April 2015 }}, ''Children of the Flames; Dr. Josef Mengele and the Untold Story of the Twins of Auschwitz'', Lucette Matalon Lagnado and Sheila Cohn Dekel, and ''Mengele: the Complete Story'' by Gerald Posner and John Ware.</ref> The twins were arranged by age and sex and kept in [[barracks]] between experiments, which ranged from amputations, infecting them with various diseases and injecting dyes into their eyes to change their color.

If one twin died from experimentation, the second twin would be brought in to be killed at the same time. Doctors would then look at the effects of experimentation and compare both bodies.<ref name=":1">Baron, Saskia, director. ''Science and the Swastika: The Deadly Experiment''.
