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.

An infection of the hair, skin, or nails caused by any one of the dermatophytes. The lesions are characterized by erythema, small papular vesicles, fissures, and scaling. Common sites of infection are the feet (tinea pedis), nails (onychomycosis), and scalp (tinea capitis).Compare: dermatomycosis. skin infection by mould-like fungi known as dermatophytesâe.g., Trichophyton rubrum, T mentagrophytes, Microsporium canis, M gypsum, rarely also Epidermophyton spp; in children, T canis is the most common agent.
