Mass screening and reliable individual measurement in the experimental behavior genetics of lower organisms.

Abstract

"Fast breeding, prolific, small organisms are pre-eminently suited for studies in the field of behavior genetics. Their value as experimental Ss is further enhanced by the method of mass screening that succeeds in combining the objective of reliable individual measurement with that of mass observation. Hence, it is now possible to achieve the experimental desiderata of efficiency, reliability, and brevity in the field of behavior genetics. The method is illustrated by experiments on the geotropic. responses of Drosophila.".
