Genotype refers to the genetic makeup of a cell. For each individual trait (such as hair or eye color), a cell contains instructions on two alleles, which are alternative forms of the gene obtained from the mother and the father.he genotype of an organism is the genetic code in its cells. This genetic constitution of an individual influences â but is not solely responsible for â many of its traits. The phenotype is the visible or expressed trait, such as hair color.
derÂ·maÂ·toÂ·phyte. A fungus that causes superficial infections of the skin, hair, and/or nails, that is, keratinized tissues. Species of Epidermophyton, Microsporum, and Trichophyton are regarded as dermatophytes, but causative agents of tinea versicolor, tinea nigra, and cutaneous candidiasis are not so classified.erÂ·maÂ·toÂ·phyte.

Nail fungus is known by a few names including âringworm of the nailâ, âdermatophytic onychomycosisâ, and âtinea unguiumâ. All of these aliases describe the same nail disease. Toenail fungus is a fungal infection of the toenails that causes the nail plate to discolor and become deformed as the disease progresses.s the fungus grows on the nail bed, it may cause the nail plate to lift and deform. This deformation may worsen over time and, in really severe cases, the nail may fall off completely or require surgical removal. It is important to treat a nail fungal infection as soon as it becomes evident that you have one.
