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.

1 Dermatophytes cause almost all fungal toenail infections. 2  Yeasts are a type of fungus that grows on the skin and nails. 3  They are normally present on the human body. 4  Things like illness, antibiotic or birth control pill use, and immune system problems may allow an overgrowth of yeast, leading to a yeast infection. You can get infected by contact with objects that have dermatophytes on them, such as clothing, shoes, nail clippers, nail files, shower and locker room floors, and carpet. 2  Dermatophytes cause almost all fungal toenail infections. 3  Yeasts are a type of fungus that grows on the skin and nails.
