Resolution of dHJs during DSBR leads to characteristic connection patterns. (A) Crossing over between copies could result in assimilation of another copy (‘attacker’) into the junction with the loss of the ‘attacker’’s barcodes (green + red pattern). (B) DSBR between linear ends and a circular copy can have two detectable outcomes: the circular copy donates barcodes without crossing over (red + blue pattern) or gets incorporated into the ‘attacking’ molecule while also donating barcodes (green + red + blue pattern). Outcomes of recombination are shown as elements of the transgene ‘subway map’.
