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.
3.Nerves are found in the peripheral nervous system, while neurons are found in the brain, spinal cord and the peripheral nerves. 4.A neuron can also be called a neurone or a nerve cell. 5.Neurons conduct nerve impulses, while nerves transmit information to various parts of the body..Nerves are found in the peripheral nervous system, while neurons are found in the brain, spinal cord and the peripheral nerves. 4.A neuron can also be called a neurone or a nerve cell. 5.Neurons conduct nerve impulses, while nerves transmit information to various parts of the body.
