0.202 to 1.71

Retro rate (Rr)

0.176 to 0.228

0.298 to 0.388

0.494 to 0.642

0.733 to 0.953

Total weight (W)

61.0% to 73.2%

53.3% to 72.6%

68.5% to 77.2%

62.9% to 76.3%

Ru + Rr

0.188 to 0.248

0.374 to 0.794

0.521 to 0.695

0.935 to 2.66

Gene duplication Rate (R)

0.257 to 0.407

0.515 to 1.49

0.675 to 1.01

1.23 to 4.23


The rates are expressed as × 10-3 per gene per million years. The lower and upper limits are calculated through all combinations of different tandemly arrayed gene (TAG) or retrogene identification criteria
