  • (N.A.) Not applicable.

  • Only paralogous L1 sequences >200 bp are included.

  • Statistically different from other segment b comparisons.P < 0.05 using t-test.

  • Statistically different from other segment f comparisons.P < 0.05 using t-test.

  • Percentage in black box represents internal duplication of segment i.
