Sequence coverage of paternal RAD loci in sons and daughters of a lab strain and b Chipwa wild-caught fish. Autosomal loci should show equal coverage in both, males and females (along black line), whereas X-linked loci should have twice the coverage in females compared to males (red line, the expectation for W-linked loci in a ZZ-ZW system is shown as blue line, corresponding to double coverage in males; lines are adjusted for differences in sample size and mean coverage). Most loci show similar coverage in sons and daughters. Note that some loci have coverage only in sons, especially in the lab strain, and are depicted in orange
