B) The new gene copies helped facilitate the evolution of more complex body plans. C) The new gene copies helped facilitate the evolution of smaller bodies.

Respuesta :

Answer: C & A

Explanation:

The HOX genes encodes important transcription factors. This factors causes protein to be made that specify cell fate and identify; embryonic primary axis, secondary axis and plays important roles in various tracts development.
