Fig 2. Synteny illustration.

Visualization of the assigned synteny types: “some synteny” ($●$), paralogues of genes found close to one duplicate are also found close to the other duplicate; “no synteny” ($●$), less than two paralogues for other genes are found close to both paralogue duplicates; “close” ($●$), duplicated genes are close in the genome; “no information” ($●$), the duplicated genes are located in small scaffolds with too few gene families close by; “conflicting syntenies” ($●$), different synteny classification found in the genomes of the different species affected by the duplication. Sand coloured boxes represent genes which have not been assigned to a gene family, pink boxes represent the gene from which synteny is being assessed; all other colour boxes represent other genes which have been assigned to a gene family.
