Answer:
The correct answers are options (A) "it is a highly complex genetic process" and (B) "it is completely governed by preexisting genetic information received by the zygote".
Step-by-step explanation:
Metamorphosis is a highly complex genetic process because it results in the adult animal having characteristics that are very different from the larvae stage. The metamorphosis process involves an hormonal reactivation development that makes dramatic morphological changes. All the hormones and receptors involved in the metamorphosis are completely governed by preexisting genetic information received by the zygote when the animals born.
