Gene	Relative Expression Male:Female ± SEM a	p-value M/F ratio ≠ 1 b
Lcaru c	1.179 ± 0.067	0.116
LcCG1970	0.967 ± 0.060	0.799
LcEph	0.975 ± 0.058	0.866

^a. Mean of 3 independent experiments. Expression was normalized to the 28S rRNA reference gene.

^b. Student's t-tests were performed for each gene separately

^c. With the exception of Lcaru, all genes are orthologs of genes located on the fourth chromosome in D. melanogaster. The D. melanogaster aru gene is located on chromosome 2.
