Hox cluster architecture in 4nF1 compared with zebrafish. We identified a total of 32 Hox genes. Nine Hox genes were present in three copies, one Hox gene was present in four copies, and one was present as a single copy in 4nF1. Copies of the HoxD9a, HoxD4a, and HoxD10a genes were pseudogenes. Black boxes represent Hox genes from Danio rerio, and “E” refers to EVX (even-skipped related gene). Aa, Ab, Ba, Bb, Ca, Cb, Da and Db refer to classes of genes
