Gene duplication and retrotransposition mapped by GIS-PETs. (A) PETs derived from transcripts (mRNA) of duplicated gene family or from gene undergoing retrotransposition events map to multiple locations on the genome. (B) PET sequence with 317 copies derived from RPL6 was mapped specifically to three locations in the human genome hg17 assembly. The location on chromosome 12 is where the gene resides, while the other two locations on chromosome 4 and 18 are where RPL6 retrotransposed regions reside.
