Mutant males show an increase in the total amount of cuticular hydrocarbons compared to control males. 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 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 compared to control females.
Homozygous males do not discriminate between male and female control flies in a courtship assay.
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.
