Answer:    Decreased levels of melatonin

Explanation:  Melatonin is a substance that is excreted at night and by which the brain sends signals that one should sleep, that is, a man / woman is feeling sleepy. When melatonin secretion decreases, the alertness increases, as is the case with Colby. Melatonin levels decrease at the base of the brain signal regardless of whether or not Colby slept enough the previous night. Feeling tired will induce some other receptors and consequent signals from the brain, but a natural decrease in melatonin throughout the day occurs normally.

This dominant nature causes this disease to be expressed even in people who have heterozygous alleles for it, which makes it easier for siblings to have this disorder, since only those who are hom0zygous recessive would not present it. However, the expressiveness of the disease may vary between siblings, as is the case shown above, where although the two siblings have the same disease, they present it in different ways.
