Figure 5. QTL for LFD and their allelic effects.

(A) Single-QTL genome-wide scan. LOD scores (y-axis) are plotted against genetic distance (cM, x-axis). Horizontal lines depict data-derived significant LOD score thresholds (permutation test): dotted line, P < 0.01 and solid line P < 0.05. Two significant peaks appear on LG1 at marker IPO7 with LOD 4.40 and LG11 at GET4, LOD 3.44. Linkage groups are shown on the x-axis and markers depicted with inner tick marks. (B) Plot of estimated phenotype averages at markers IPO7 and GET4. The y-axis indicates phenotype values on logarithmic scale. The x-axis depicts the three genotypes at each marker – FF refers to F₂ homozygous for N. furzeri GRZ allele, FK stands for heterozygous F₂ and KK for F₂ homozygous for the N. kadleci allele. Bars at each genotype are standard error of mean. Significant differences in phenotype mean between genotypes are shown by asterisks (**) =P<0.01, (***) = P<0.001, (****) = P<0.0001.
