QUESTION 2
As certain lineages of animals evolved more and more complexbody plans, what has happened to the Hox genes of theseanimals?
The number of Hox genes has been reduced
The more complex the body plan, the greater the number of Hoxgenes.
Complex body plans have more inactive Hox genes
There is no correlation between body plan complexity and Hoxgenes
