Abstract
Sex-linked meiotic drivers limit the inheritance of the alternate sex chromosome in the heterogametic sex, subsequently skewing the ratio of males to females in the offspring. They consequently have large impacts on genome evolution, adaptation, and the emergence and maintenance of sexually selected traits. Detecting the molecular basis of meiotic drive is complex. It is affected by both the common occurrence of inversions housing a driver as well as the transcriptomic and cell type heterogeneity of the gonads. Herein, we utilise DNA-Seq to investigate the genetic basis of a sex-linked meiotic driver in the Malaysian stalk-eyed fly, Teleopsis dalmanni. These data are generated from wild adult flies from the Gombak District of Peninsular Malaysia.

Description of the data and file structure
Samples
Flies were reared at University College London from a wild-caught population originating from the Gombak Valley, Malaysia. All flies and larvae were incubated and reared at 25°C and fed on a diet of sweetcorn. To ensure known genotypes of samples, a homozygous drive (SR) population is maintained through a series of crosses as described in (Presgraves et al., 1997). Eight adult males, four standard (ST) and four with drive (SR), were sacrificed before the dissection of both testes in iced phosphate-buffered saline (PBS). These adults were all virgins, reproductively mature, and reared from egg lays collected on the same day.
Tissue collection, dissociation, and single-cell sequencing
Testis pairs were individually dissociated by incubation in a collagenase-TrypLE lysis solution (10mg/ml collagenase in 10X TrypLE) at 37.5°C for one hour with three sets of mechanical dissociation by triturations of wide then narrow bore Pasteur pipettes. Digestion was inhibited by the addition of iced Schneider’s Serum. The solution was then gently pipetted up and down with a narrow-bore Pasteur pipette before filtering through a 35μm filter pre-rinsed with Schneider’s Serum. The sample was then spun in a swing bucket centrifuge for 5 minutes at 1000xg and 4°C. The supernatant was removed and the pellet resuspended in 50μl of iced PBS with gentle pipetting of a wide-bore pipette. To count cells, 10μl of the suspension was combined with 10μl of trypan blue and placed onto a humidified haemocytometer plate before counting in triplicate.
10X Genomics Chromium transcriptome libraries were generated at the NERC Environmental Omics Facility (NEOF), Liverpo, before sequencing with Illumina NovaSeq using S2 chemistry, aiming for recovery of ~10,000 cells per sample and ~20,000 reads per cell.
