FIGURE 1 Distribution of short (ROHσ = 0.05−0.2 Mb), medium (ROHμ = 0.2−0.7 Mb), and long (ROHλ = 0.7−7.9 Mb) runs of homozygosity along the longest scaffold analyzed (~7.9 Mb) for individuals (horizontal bars) from the reference S. tergeminus population (STER—black ) and two S. catenatus populations (PROF—blue ; CEBO—purple ) with low and high levels of inbreeding. ROH size classes are indicated by gradual color shadings (see box legend) for each population
