Figure 2. Manhattan plots of SNP positions on the male Pacific lamprey gametic genome of a) chromosome 1 and b) chromosome 2.F ST values among range-wide collections generated in LOSITAN are indicated on the primary y-axis (gray). The criticalF ST value of 0.07 is indicated by the gray dashed line (SNPs above this line were considered outliers P > 0.995). The -LOG10(P) values from association testing are indicated on the secondary y-axis (black), and show values from a) testing gonad size in females for the WFA♀ sample and b) testing adult body size for the T_BON sample. The critical value of 1.3 -LOG10(P) indicates the adjusted P -values using the Benjamini and Hochberg (1995) false discovery rate for alpha = 0.05.
