Developmental modularity
A) allows one part of an animal's body to change independent of another.
B) is controlled by a single "switch."
C) can be independent of Hox gene expression.
D) is a consequence of the action of the genetic tool kit.
E) Both a and d

Question

Quizplus · Accepted Answer

Developmental modularity allows one part of an animal's body to change independently of another, which is a characteristic of option A. This independence is a consequence of the action of the genetic tool kit, which is mentioned in option D. Therefore, the best choice is E, which includes both A and D. Option B is incorrect because developmental modularity is not controlled by a single "switch," and option C is incorrect because Hox gene expression is integral to the control of developmental modularity.
