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.[1]
