Nervous system
Explanation:
The nervous system in humans work together to collect information about the external environment because they consist of the brain, spinal cords and neurons. They collect information from external environment and those information travels through neurons from sense organs like eyes, ears, skin e.t.c as a form of electrical impulses.

Hence a cross between two individual that dominos of the allele will breed true type.
