      The total amount of cuticular hydrocarbons is the same in mutant and control males. The mutant males show a significant decrease in the relative proportion of desaturated cuticular hydrocarbons compared to control males.

      Mutant females show an increase in the total amount of cuticular hydrocarbons compared to control females. They show a significant decrease in the relative proportion of desaturated cuticular hydrocarbons and a significant increase in the relative proportion of linear cuticular hydrocarbons compared to control females.

      Homozygous males show a normally high ability to discriminate between male and female control flies in a courtship assay, having a significantly higher courtship index towards females than towards males.

      (Houot et al., 2010)

      Mutant females have defective cuticular hydrocarbon (CH) profiles; the desaturation index (DI) in females is significantly different from both wild-type controls and the desat11573-1 progenitor allele.
