  1. N (C): Number of chimeric retrocopies; N (i): Number of intact chimeric retrocopies; N (f): Number of frameshift chimeric retrocopies; N (s): Number of chimeric retrocopies have premature stop codons; N (f & s): Number of chimeric retrocopies both have frameshifts and premature stop codons; N (0.5): Number of chimeric retrocopies have omega values (between them and corresponding parental genes) less than 0.5 significantly; chimeric type(s): the chimeric type are represented in roman numbers (Figure1 for more information), inside brackets are number of chimeric type.
