Two trends of expression patterns of duplicated SET gene pairs. X-axis indicates representative tissues, organs or treatments and Y-axis represents scale. Purple box: both copies of the duplicated pair show complex expression patterns. Black box: one copy of the duplicated pair has low transcription in all tissues compared relative to the other copy.
