From: Phylogenomic analyses of KCNA gene clusters in vertebrates: why do gene clusters stay intact?

Figure 1

Phylogenetic scheme of KCNA cluster evolution. Non-connected genes indicate missing linkage/genomic data. Grey squares show hypothetical genes that most likely exist, but are still missing from the current versions of genomic databases. The boxes include genes that are not part of KNCA clusters. The teleost state is hypothetical since we found duplicated KCNA4 genes in Gnathonemus petersi and duplicated KCNA7 genes in Oryzias latipes, but no teleost studied so far showed the full set of duplicated genes.
