Gene expression across domesticated species.

<p>A and B) For each of three models, the figure shows the number of genes that match or exceed the p-value for the domestication factor and that are expressed in the same direction in domesticated animals. The thick black line shows the real data. Each grey line shows the result from one of the possible extreme permutations (see <a href="http://www.plosgenetics.org/article/info:doi/10.1371/journal.pgen.1002962#pgen.1002962.s013" target="_blank">Note S1</a> for details). p = 1 is included to show the effect of only requiring genes to be expressed in the same direction, irrespective of significance. vsd: variance stabilized data. A) joint analyses of dogs, pigs and rabbits. B) As in A, but including guinea pigs.
