Mendelian inheritance display. Display board showing some of the possibilities for colour inheritance in guinea pigs with white and black colouration. The three possibilities shown are: white plus white to produce white; black plus black to produce black; and white plus black to produce hybrid black. This display, produced by the American Eugenics Society (AES, founded 1923), was used in its campaigns to educate the public about genetics. Eugenics is the controversial practice of selectively improving the genetics of human populations. The AES and other eugenics organisations were criticised for their racist assumptions. Photographed in 1926.
