Sequence Traces of a SNP Cluster with Three Consecutive SNPs
The top is a homozygous sample and the bottom a heterozygous one. The Phred quality score is labeled on top of each base. In the heterozygous sample, the three HQDPs around the three heterozygotes are labeled with red lines at the bottom. The flanking bases used for calculating genotype quality class of the highlighted heterozygote in the middle are marked by rectangular boxes, which do not include any HQDPs. The flanking bases used to assess background noise in the flanking region are labeled with brackets at the bottom.
