Table 3. A111T date estimation using 1000 Genomes Project data.
| Population | Chromosomes | Difference Total | Effective Sample Size | Date, kya (95% Confidence Limits) |
|---|---|---|---|---|
| Combined | 1013 | 822 | 19 | 7.8 (4.8−12.2) |
| CEU | 165 | 110 | 13 | 6.4 (3.4−11.4) |
| GBR | 178 | 136 | 14 | 7.4 (4.1−12.4) |
| FIN | 180 | 160 | 10 | 8.6 (4.5−15.1) |
| TSI | 193 | 105 | 18 | 5.2 (2.9−9.0) |
| IBS | 28 | 24 | 9 | 8.3 (4.2−15.0) |

Human-chimpanzee alignment contains 1227 differences in aligned length of 125,531, of total 127,419 nt in C+D region. When a divergence date of 6 million years ago is used, this corresponds to a per-site mutation rate of 8.1 × 10−10 year-1. Dates shown are not corrected for undercounting of rare polymorphisms. For combined C11 sample, distribution of variants suggests that tabulated dates should be multiplied by a factor of 1.58. kya, thousand years ago.
