Abstract

Flies were divided into two groups on the basis of the number of their bristles, and raised under different environmental (temperature) conditions. In each generation, offspring of the two groups were retained in their group or transferred to the other group, depending on the number of their bristles. After nine generations it was found that the genetic component of the intergroup difference was 42 percent; the portion of the intragroup variance that was genetic phenomena.
