Structural variation in the D. albomcians genome. (A) The male to female ratio of different structural variants (insertions, deletions, tandem duplication, dispersed duplications) on each chromosome. (B) The proportion of tandem duplications overlapping with protein-coding regions on each chromosome for males and females (no tandem duplications on the fourth chromosome overlapping coding regions were observed in females).
