Syntelog

Syntelog: a special case of gene homology where sets of genes are derived from the same ancestral genomic region. This may arise from speciation events, or through whole or partial genome duplication events (e.g. polyploidy). This term is distinct from ortholog, paralog, in-paralog, out-paralog, and xenolog because it refers only to genes' evolutionary history evidenced by sequence similarity and relative genomic position.

Example

Comparison between two genomic regions of Arabidopsis thaliana derived from its most recent genome duplication event. Syntelogs are indicated by red lines connecting regions of sequence similarly (red boxes):

gollark: I suggested to my school that we be allowed to learn from home a few days a week, but apparently government says no to *that*, too.
gollark: It's entirely in person here and the government requires people to come.
gollark: Vaguely relatedly, I'm going back to school tomorrow, it seems.
gollark: They aren't even that cheap compared to used hardware.
gollark: I mean, any recent Intel/AMD CPU and tons of ARM SoCs have hardware video encoding.
