If crossing over does not happen the product is parental gametes. Meaning there is less genetic variation.
<u>Answer</u>: Option 3 Coevolution
<u>Explanation</u>:
<em>Coevolution</em> is a process in which two individuals reciprocally affect each other's evolution. In this process the interacting species exert selective pressures on each other thus, affecting their evolution. Due to this reciprocal adaption they become so close that the evolution of one species is affected by the other.

Answer:
The true statements regarding the adrenal glands' relationship with the autonomic nervous system are:
a. The adrenal cortex is an extension of the parasympathetic nervous system.
c. The adrenal glands are strictly nerve tissue.
d. The parasympathetic division stimulates the adrenal cortex to secrete glucocorticoids.
e. The adrenal medulla is penetrated by the fibers of the sympathetic nervous system.
Explanation:
The levels of the central nervous system which play important roles in influencing the autonomic nervous system include cerebral cortex, hypothalamus, brain stem, and spinal cord. Usually, epinephrine (adrenaline) and norepinephrine are released into the blood stem when stress or a threat occurs. This alert serves as a warning signal and defense system. The purpose is to maintain homeostasis.
