A A 2D cartoon of a possible 3D configuration for genome A. Adjacencies between syntenic blocks are classified by physically close regions, which are marked by dashed circles and labeled by the alphabet \(\{a,b,c,d\}\). B Genome A after a reciprocal translocation has occurred at position b. C Genome A after an excision has occurred at position b
