From: Different evolutionary patterns between young duplicate genes in the human genome
Comparison between fast-evolving copies and slow-evolving copies. The figure shows that fast-evolving copies have more cases with substitutions distributed evenly along the sequence than slow-evolving copies. Fast-evolving: the copy that has evolved faster than the other in each duplicate pair. Slow-evolving: the copy that has evolved slower than the other in each duplicate pair. Even pattern: a sequence that has evenly-distributed substitutions along the sequence. Uneven pattern: a sequence that has unevenly-distributed substitutions.
