Syntenic depth refers to the number of times a genomic region (or genome) is syntenic to regions in another genome.
Tools in CoGe for classifying and quantitating syntenic depth:
Examples:
| Organism | Syntenic Depth | Dotpot |
| E. coli DH10B to MG1655 | 1:1 | |
| Human-Chimp | 1:1 | |
| Rice-Brachypodium | 2:2 | |
| Sorghum-Maize | 2:4 | |

These tables show the number of gene participating at a particular syntenic depth and are used to infer the number of polyploidy events between two genomes.
