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.

Fungal forms vary: the most commonly known are mushroom-like in appearance or form spongy, creeping growths. The individual, tubular threads are called hyphae, while a mass of threads is called a mycelium.pecialized hyphae, known as rhizoids, anchor some forms of fungus to the substrate. Parasitic fungi have similar specialized hyphae known as haustoria, which function in nutrient absorption (from the cells of other organisms) while anchoring the fungus.
