Which of the following likely has the most Hox genes?

Question

Quizplus · Accepted Answer

Dolphins, being mammals and thus more complex organisms in terms of body plan and structure, likely have the most Hox genes. Hox genes are a group of related genes that control the body plan of an embryo along the head-tail axis. As organisms increase in complexity, particularly in the vertebrate lineage, they tend to have more Hox genes to support the development of their more complex structures.
