You sequenced a tumor genome and a healthy tissue genome. you find that there are twice as many reads mapping to a region on chromosome 13 for the tumor sample versus the healthy cell sample. which of the following is most consistent with this observation?
A. the tumor has an inversion in chromosome 13
B. the tumor has a deletion in chromosome 13
C. none of the answers is correct; this must be an experimental error
D. the tumor has a translocation between chromosome 13 and another chromosome
E. the tumor has a duplication in chromosome 13
