Analysis of the Expression System of Gene radius incompletusin Drosophila melanogaster The genetic expression system of generadius incompletus was studied by substituting regions of chromosome 3 from line th st ri sr ca, which has drastically reduced riexpression, to regions of chromosome 3 from a “selection” line ri s – having very high expression of this gene.

Abstract

The genetic expression system of generadius incompletus was studied by substituting regions of chromosome 3 from line th st ri sr ca, which has drastically reduced riexpression, to regions of chromosome 3 from a “selection” line ri s – having very high expression of this gene. Virtually all chromosome 3 was shown to carry polygenes controlling phenotypic expression of oligogenic mutationri. Chromosome regions making large (as well as small and even negative) contributions to sizes of the distal and proximal fragments of the latitudinal wing vein were found. These results suggest that the genetic system of expression does not correspond to the generally accepted postulates of K. Mather on equal, small, and additive contributions of polygenes.
