Abstract
The selective effect of the ecological parameter "food medium" upon the gene pool of Drosophila melanogaster was investigated in nine cage populations by estimating the allozyme frequencies of the a-Gpdh and Adh loci. The differentiation observed was found to depend dramatically upon the action of the above mentioned environmental factor. Small differences may be mainly attributed to the effect of the differing genetic backgrounds of each gene pool. When the environment was restrictive, a dramatic gene pool differentiation was observed. A discussion is provided bearing upon the observed induction of a process which involves large groups of coadapted genes upon which selection actually acts. Furthermore, the role of nutrition, and especially yeast, was found to have a profound effect upon the observed genetic differentiation of the gene pool of D. melanogaster.
