The genetic analysis of factors influencing the lethality associated with the scute inversions of Drosophila melanogaster

It has been previously established that inviability is associated with X/0 males carrying a scute inversion X chromosome. Explanations of this phenomenon suggest that the lethality may be due to a position effect suppression of the rRNA cistrons. This thesis provides an alternative explanation of th...
