Fig 3. CGV shows conservation of linkage groups in the absence of conservation of gene order.

(A) CGV ideogram view of alignment between Drosophila albomicans and Drosophila melanogaster genomes. Alignments are restricted to a single chromosome or chromosome region.

These chromosomes align to each other across their length, but the alignment is broken into multiple short segments which are extensively rearranged.

Alignments show less scatter and more of a diagonal slope, indicating more conservation of sequence order between these two species’ genomes. https://www.ncbi.nlm.nih.gov/genome/cgv/plot/GCA_021014325.1/GCA_010994315.2/41175/466999
