Genotypes view. HomozygosityMapper also displays the single genotypes of all samples. Here, the markers are placed on the x-axis while the samples are on the y-axis, with the patients on top and with red IDs. Genotypes are colour-coded: grey, unknown, blue, heterozygous, red, homozygous stretches (colour saturation reflects the length). This figure also reveals the presence of a single heterozygous marker within the homozygous region (possibly a genotyping error and ignored by HomozygosityMapper). The patient on the bottom is from another family than the first two and does not share the same haplotype over the whole homozygous stretch. This can be seen from the genotypes with the diagonal bar indicating the less abundant of the homozygous genotypes. Users are free to change the limits of the region and can subsequently submit this region to GeneDistiller.
