Cartoon of fractionation following a genome duplication event. Colored circle represent genes along a genomic region. Following a genome duplication, all genomic content including chromosomes and their underlying gene content is contemporaneously copied. Over evolutionary time, many duplicate genes (but not all) are lost from one homeologous region or its partner region. This returns the overall gene content of a genome to one that is more similar to the pre-duplicated ancestor, but the overall genomic structure has changed drastically. Genes that are retained in duplicate can be used to detect synteny by their collinear arrangement in two or more genomic regions.
