Fig 3. Manhattan plots of genome-wide (di) measures of overlapping 500Kb windows for three cat breeds.
Each dot represents a window of 500 Kb (total 9108 windows) and the horizontal dashed red line indicates the 99th percentile threshold, which distinguishes the top 92 windows. (a) Genome-wide survey of selection for the America Curls, which is a breed defined by backward curled ears. A number of overlapping windows clearly show a signal on Chr. E3. (b) Genome-wide overview of selection for Maine Coon cats, which is a breed recognized by an overall large size and facial features such large oval eyes and a square chin. Visible signals of overlapping windows are shown on Chrs. A1 and A3. (c) Signal of selection for the Turkish Van breed, which is acknowledged for a coat color pattern named after the breed, “Van”. This pattern appears in an overall white coat with distinct coloration in parts of the head and tail. Few overlapping windows were detected on Chrs. A2 and E3.
