Fig 1. SV formation mechanisms of 66 Chinese pigs.

(A) Pie chart of formation mechanisms (33,482 SVs) of recalibrated deletions. The inner and outside circles represent the lengths and occurrence numbers of all recalibrated SVs, respectively. (B) Length distribution of different forms of deletions. Color reference is same as in A. (C) Formation mechanisms of deletions in SV hotspots. (D) Distribution of deletions generated by different formation mechanisms in the whole genome. The highlight red, blue and black regions represent hotspot of NHR, TEI and mixed distributions, respectively. Color reference of the inner circles is same as in A.
