Examples of different levels of polymorphic STRs. The STRs were retrieved from ENSG00000267127 and ENSG00000110799 for all 7 human genomes. NA12878 represents the CEU child, NA12891 the CEU father, NA12892 the CEU mother, NA19238 the YRI mother, NA19239 the YRI father, and NA19240 the YRI child. (a) Aligned polymorphic STR patterns and flanking sequences for ENSG00000267127, which is contained in the human-unique gene set. Left red box shows the differences between each family, while the right orange box represents inheritance relationships within a family (identical STRs for both mom and daughter). (b) Aligned polymorphic STR patterns and flanking sequences for ENSG00000110799, which is contained within the CODIS gene set. Similar conditions for a previous example and the highlighted segments in blue background represent aligned flanking sequences.
