Lineage-specific Alu Insertions
Human | Human/Chimp ratio | Chimpanzee | |
|---|---|---|---|
| Observed inserted total | 101 | 2.20 | 46 |
| PCR tested | 78 | — | 43 |
| Fixed present | 63 | — | 26 |
| Observed polymorphic | 16 | — | 18 |
| Observed polymorphic fraction | 0.21 | 0.50 | 0.41 |
| Adjusted polymorphica | 31-33 | — | 35-37 |
| Adjusted polymorphic fraction | 0.33-0.34 | 0.56-0.60 | 0.57-0.59 |
| Adjusted inserted total | 116-118 | 1.84-1.93 | 61-63 |
a Adjusted polymorphic fraction was calculated based upon simulation of the frequency of polymorphic Alu elements observed in a given genome by sampling alleles from a uniform frequency distribution (see Methods). Ranges indicated were generated based on 95% confidence intervals derived by simulation.
