Hox4 Hox5 Hox7 Hox8 Hox10 e mouse Hox genes are expressed in specific domains along the anterior-posterior axis. In the figure on the right, the expression domains of Hox genes 4 through 10 in the cells that give rise to the vertebral column are indicated by the colored squares Hox6 Spinal cord Suppose to study the function of the Hox genes, Tim, a graduate student, examined the vertebral skeletons of mice where all copies of a particular Hox gene were knocked out Thoracio Cervical Hindbrain Midbrain Lumbar Wild type mice have ribs on the thoracic vertebrae but not on the cervical vertebrae. In contrast, the knockout mice had no ribs on the first thoracic vertebrae and only partial ribs on the second thoracic vertebrae, indicating that these thoracic vertebrae had developed like cervical vertebrae. What was the genotype of these knockout mice? Sacral Forebrain Hox6/Hox6
