Confirmation of the Sphaerodactylus townsendi sex chromosome on LG3. (A) RADseq M/F FST scan in 500 kb windows (zoomed in on LG3 from Figure 2); (B) M/F read depth differences across the length of LG3; (C) male and female nucleotide diversity (π) along LG3. The same set of male-specific RADtags mapped to LG3 are denoted by orange ticks along the bottom of each graph (same in each panel). (D) Gel images from a subset of these markers illustrate that they are located on the Y chromosome. Picture of an adult male S. townsendi scaled with a penny, USA currency (diameter = 19.05 mm).
