In Drosophila melanogaster a series of dominant modifiers of the X‐linked eye‐colour gene zeste ( z , yellow eyes in females, wild‐type red eyes in males) and a series of new and previously isolated Minutes (short fine bristles, prolonged development, homozygous lethals) have been examined for their ability to modify the eye colour in z males, where the yellow eye phenotype is evoked by different duplications or triplications of white ( w ). Most Minutes suppress the yellow eye colour of z males with the long duplication Dp ( 1: 1 ) w rG (= Dp ( z‐w )) but have no effect if the z males bear the small intragenic aberrations w ts or Tr ( w + R ). The suppressors of z , denominated Su ( z )‐genes, have a strong effect on z w ts , turning the yellow‐brown male phenotype to red wild‐type eye colour. z Dp ( 1: 1 ) w rG is also drastically suppressed by the Su ( z )‐genes, but only the strongest suppressors are able to modify the eye colour of z Tr ( w + R ) males.
