Figure 12From: The dynamics of vertebrate homeobox gene evolution: gain and loss of genes in mouse and human lineagesThe SHOX gene has been lost in rodent genomes. The SHOX gene is located in syntenic regions of human (X and Y chromosomes) and chicken (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
