Figure 5.
Genetic mapping of gill raker length reduction. (A) Lengths of three ventral row 1 gill rakers were measured at lateral, middle, and medial positions. cb1, ceratobranchial 1. Scale bar = 500 um. Manhattan plots of QTL mapping of gill raker length in the FTC cross (B) and the BEPA cross (C). Three gill raker lengths were mapped: lateral (blue), middle (black), and medial (red). LOD is shown as a function of genetic position. The significance thresholds (α = 0.05) are shown with a dotted line.
