"Segmental deletion" seems to be the correct answer.
Explanation:
A special sequence range of approximately [tex]1\times 10^6[/tex] bp scattered segmental transposable elements containing DNA over a system or zone of [tex]2\times 10^6[/tex] bp edge.
About [tex]1.6\times 10^6[/tex] bp, including that of the special sequence DNA, is destroyed if recombination happens between some of the segmental duplications.
