Figure 2

Genome-wide mapping reveals homozygous regions on chromosome 22 in pointing dogs. Genome-wide mapping reveals homozygous regions on chromosome 22 in 26 pointing dogs (GM, Large Munsterlander; LW, Weimaraner) as compared to 26 herding dogs (BDP, Berger des Pyrenées; SD, Schapendoes). Homozygosity peaks were revealed by Homozygosity Mapper analysis in pointing dogs (A). Homozygosity peaks for part of magnified chromosome 22 (B): Genomic areas with homozygosity scores (HS) of >0.8 are depicted in red color. Regions with HS = 1.0 were further analysed in detail. Genotyping results for the corresponding regions are depicted in different colors for the individual dogs (C; blue = heterozygous, red = homozygous, dark to light shades of red indicate longer and shorter homozygosity stretches, respectively; gray = unknown; color patterns are predefined by Homozygosity Mapper). Genotypes homozygous for the minor allele are marked with black diagonal bars. Genes included are depicted as black bars including their respective abbreviated designations (D).
