Summary of the identification and sequence analysis of the microsatellite DNA sequences. Red bars indicate the allele size range in the HGDP-CEPH data set, for which h and H are the smallest and largest allele sizes, respectively. Blue bars indicate the allele size range in the Marshfield primer data set, for which m and M are the smallest and largest allele sizes, respectively. The BLASTN fragment size in the human RefSeq database is denoted by x. A, B, and C refer to the repeat units of the different STR regions in a microsatellite sequence, with a, b, and c being the number of times they are repeated, respectively. N indicates a nucleotide not within an STR region, with n being the number of nucleotides separating two STR regions. For microsatellites with three STR regions, n₁ and n₂ respectively represent the numbers of nucleotides separating the first and second, and the second and third, STR regions. Key: ∧, and; ∨, or; ROS, range overlap score.
