From: Different evolutionary patterns between young duplicate genes in the human genome
The Ka/Ks ratio distribution of young human duplicates. The x axis is the Ka/Ks ratio on the branch leading to one human duplicated gene. The y axis is the number of genes within a Ka/Ks bin. (a) All genes from the 250 pairs, a total of 500 sequences. (b) The fast-evolving duplicate copies of 250 pairs, a total of 250 sequences. (c) The slow-evolving duplicate copies of 250 pairs, a total of 250 sequences.
