Abstract

INVESTIGATION of the relationships between population size and gene frequency in laboratory studies of Drosophila have been limited to small breeding groups (usually of less than one thousand individuals) because of the difficulty of estimating population number. Direct counts can be made when units of the types described by Reed and Reed1 and Buzzati-Traverso2 are in use, but the environment in these systems lacks constancy. The former has been modified3,4 for work on larger populations; but with this design there remains the possibility that migration between sections of the cage might be somewhat restricted. For that reason it was felt that the following technique might be of interest to other workers in this field.
