Detection of small duplicated genomic segments. (A) Detection of 2HOM blocks in real and random genomes. In red, a duplicated block of two homologous genes AB is shown. (B) Detection of 3HOM blocks in real and random genomes. In red, a duplicated block of three homologous genes ABC is shown. In this example, also two 2HOM blocks are identified, namely AB (dark green) and BC (light green). (C) All possible situations where the gene orientation in a 2HOM block is conserved and not inverted. (D) Possible situations where the gene orientation in a 2HOM block is conserved but where one segment is inverted.
