A SNP map for chromosome arm 3R. A plot of the polymorphisms found on 3R is shown. The x-axis is approximately co-linear with the molecular map of the chromosome, with each region representing one section of the genomic scaffold. The estimated cytological positions are indicated underneath. The y-axis shows the number of polymorphisms found in a given region. For a detailed description of the individual polymorphisms, see Table 1. Seventy-three polymorphisms are distributed along the whole arm, with an average distance between them of 370 kb.
