Comparison of pooled sequencing data from three fishes in the order Gasterosteiformes Raw sequence reads

Genome scans were compared among three species in the stickleback order (Gasterosteiformes) to detect shared genetic patterns. Two marine populations of threespine stickleback (Gasterosteus aculateus) and tubesnout (Alurhychous flavidus), and four freshwater ninespine stickleback (Pungitus pungitus) populations were whole genome sequenced in pools of 30 - 52 individuals. This whole genome data was then analysed within a species to calculate genetic diversity statistics. Patterns of genetic diversity were then compared among species to look for similarities. Overall no similar patterns were found among species, demonstrating how the balance of evolutionary forces can shape genetic diversity in distinct ways.
