Distribution of recently duplicated common carp genes in the zebrafish genome.
The outer circle represents 25 zebrafish chromosomes. (a) The common carp RDG loci in the zebrafish genome. Red and green represent two RDGs. (b) The cDNA identity distribution of RDGs (from 0 to 100%). (c) The protein identity distribution of RDGs (from 0 to 100%). The more similar two copies are, the higher the bar. The cDNA and protein identity distributions demonstrate high conservation between two RDGs. (d) Ks of the RDG pairs. (e) Ka/Ks of the RDG pairs. The lower bar indicates higher selective pressure.
