Associations between Variation in X Chromosome Male Reproductive Genes and Sperm Competitive Ability in Drosophila melanogaster

Table 1

Candidate male reproductive genes on the X chromosome. Criteria for selecting genes for DNA sequencing and association testing are presented. Testes/whole body and male accessory gland (MAG)/whole body columns present ratios of expression from FlyAtlas data.

CG15035 ^a	15.9	0.1	Protein phosphatase
CG12470 ^a,d	7.6	0	Unknown
CG9806 ^c	0.5	92.5	Membrane alanyl aminopeptidase
CG1559 ^c	0.7	1.00	DNA/RNA helicase (Upf1)
CG9156 ^c,d	10.9	0	Protein phosphatase 1 (Pp1-13c)
