Sections of DNA that are conserved among species can be identified by performing a zoo blot. We use short fragments from the region as labeled probes to test for homologous DNA from a variety of species by Southern blotting.

Technique that allows genomic fragments to be rapidly scanned for the presence of exons is called exon trapping.

When pairs of human 23 and mouse 20 homologs are compared, the genes located on either side also tend to be homologs. This relationship is called synteny
