title: Radiation-Induced Increases in Fitness in the Flour Beetle Tribolium confusum.
abstract: Polygenic mutations were induced in an inbred strain of Tribolium confusum by exposure to 500 roentgens of gamma radiation. Female progeny of irradiated males bearing induced mutations in the heterozygous state produced significantly more viable offspring than control female progeny of nonirradiated males.
