  1. In the column ‘Movement’, ‘10 < −6’ means a new gene on chromosome 10 is retroposed from a gene on chromosome 6, for example. ‘Intron (−)’ and ‘Intron (+)’ are the numbers of intron losses and intron gains in retrocopies, respectively. For ‘Evidence’, ‘A’, confirmed by RT-PCR; ‘B’, supported by convincing transcription evidence. ‘*’ means that the newly evolved intronic regions of XXyac-R12DG2.2 and AC019016.1 could be spliced in two patterns, respectively.
