title: SDfxSHm F2 slow-growing
design: F2 hybrid clutches were hatched together  in petri dishes, and individuals scored for date of metamorphosis into  copepodid stage, and each frozen separately. After ~3000 individuals were  scored, the 10% slowest were pooled for library prep and sequencing. Library  was prepared using the Illumina Nextera kit, with gel size-selection in the  range 350-500bp.
