C) It reduced morphological diversity of simple forms of life.
D) It allowed the reversal of the head-tail orientation of animals.

Question

Quizplus · Accepted Answer

Duplication of homeotic Hox genes has played a crucial role in the evolution of novel forms by providing the genetic material necessary for the development of new morphological features. This genetic redundancy allows for mutations in one copy to explore new functions without losing the original function, leading to increased complexity and diversity in organisms.
