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.

At their root are fungi, not the bacteria or viruses that cause other infections. Technically speaking, ringworm is a dermatophyte, says Weinberg. A dermatophyte is simply a type of fungi that can cause skin, hair, or nail infections. Candida is a yeast, says Weinberg. These fungi can cause infections on many areas of the body. These fungal infections affect some of the same body parts but also different ones, Stein Gold tells WebMD.
