Fig. 5From: During evolution from the earliest tetrapoda, newly-recruited genes are increasingly paralogues of existing genes and distribute non-randomly among the chromosomesThe distribution of newly recruited genes across the autosomal chromosomes, measured as MAD values – see Methods - as a function of phylostratum number, for eight animal species. The horizontal lines drawn are the median, and the 25% and the 75% limits, computed for all the data through to phylostratum 12, the euteleostomii (the jawed fish)Back to article page
