Any sensation you receive anything you see, hear, touch, taste, or smell-activates sensory neurons, which takes the message to the brain. Each time you move any muscle of your body motor neurons are at work. Interneurons play crucial role in the inhibition of impulses between one brain region and another. Monogenic: the hereditary passing on of traits determined by a single gene. Polygenic: the process by which many genes interact to create a single characteristic. Heritability: the extent to which a characteristic is influenced by genetics. Fraternal twins: twins that develop from two different eggs fertilized by two different sperm.
