• This investigation was carried out to clarify whether or not the induced detrimental genesor gene blocks interact with each other, by means of using Drosophila as the material. It was ascertained that an interaction between genes or gene blocks for the viability in the 2^<nd> and the 3^<rd> chromosome exists. It was also demonstrated that the spectra of viability, that is, the distribution of frequencies in viability, formed bimodal curves for irradiated 2^<nd> chromosomes, for irradiated 3^<rd> chromosomes, and for both irradiated 2^<nd> and 3^<rd> chromosomes. The spectrum of viability in the isogenic lines is discussed with inference to these results. Further, the genetic load of an organism having two interacting loci is calculated, based on the theoretical model and based on the obtained results.
