Abstract:
The analysis shows that apart from the relative hyperpigmentation of the "black" skin (genetically determined and variable according to ethnic group, age, sex and solar exposure), which determines the secondary dyschromic reactions to the majority of the dermatosis, and, except the differences of frequency of diseases related especially to geographical or epidemiologic determinisms, there is no true specificity although some entities are little or not described on "white" skin (dermatosis papulosa nigra, acral punctuated hyperkeratosis, progressive macular hypomelanosis of the trunk, acne keloidalis, pseudofolliculitis barbae, aïnhum...).

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...

Pigmentation
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...
