FIG. 4.—
Ages of Abpa paralogs in MYR estimated by Laukaitis et al. (2008) were plotted below the physical map of the Abp gene region. Older paralogs plot closer to the left and right boundaries, whereas younger paralogs are in the interior of the region. Colored bars above the linkage group represent the five clades described by Laukaitis et al. (2008).
