Figure 9From: The dynamics of vertebrate homeobox gene evolution: gain and loss of genes in mouse and human lineagesThe Ventx gene has been lost in rodent genomes. The VENTX gene is located in syntenic regions of human, rat, dog and chicken genomes (orange arrows), but absent at the equivalent location in mouse and rat. Non-homeobox genes used as indicators of chromosomal synteny are shown as grey arrows.Back to article page
