Fig. 3From: Construction of a high-density genetic map and mapping of a sex-linked locus for the brown alga Undaria pinnatifida (Phaeophyceae) based on large scale marker development by specific length amplified fragment (SLAF) sequencingQTL analysis of the sex phenotype on linkage groups. The x-axis indicates the linkage groups and the marker order. The horizontal gray line indicates the threshold of the LOD score (4.1) for significance (P = 0.01) at the whole genomic levelBack to article page
