Summary of the identification and sequence analysis of the chimpanzee microsatellite DNA sequences. The blue bar indicates the PCR fragment length range in the chimpanzee genotype data, for which g and G are the smallest and largest PCR fragment lengths, respectively; the red bar represents the PCR fragment length range when extended by 6 bp on each side. The ePCR fragment length in the UCSC chimpanzee reference sequence is denoted by x. The quantities p_f,l, q_f,l and q_f,i refer to the length, BLASTN alignment length, and BLASTN sequence identity of the forward primer, while p_r,l, q_r,l and q_r,i refer to the exact same quantities for the reverse primer. A, B, C, D refer to the repeat units of the different STR regions in a microsatellite sequence, with a, b, c, and d 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 consecutive STR regions. For microsatellites with three and four STR regions, n₁, n_2, and n₃ represent the numbers of nucleotides separating the first and second, the second and third, and the third and fourth STR regions, respectively. Key: ∧, and; ∨, or.
