We can observe a phenotype whether or not we understand the genetics behind it. In real life, there is a gene called HERC2 that works like I described, and most people with blue eyes have the broken allele of this gene.
Nerves, Neuroglia, and Ganglia. A nerve is a bundle of fibres (axons and/or dendrites) outside the CNS. Neuroglia are cells of the nervous system that help protect and support it. Ganglia are groups of nerve cell bodies lying outside the CNS.
What is Neuropathy? Neuropathy is basically derived from the two words âneuroâ referring to the nerves and âpathyâ referring to the disease. The more commonly used term is peripheral neuropathy, referring to the damage to the nerves of the peripheral nervous system. The reason for this condition may vary from disease of the nerves to trauma and it can even be a result of a systemic disease.
