First we must appreciate that genes do not act in isolation. The genome in which a genotype is found can affect the expression of that genotype, and the environment can affect the phenotype.Not all pairs of alleles will have the same phenotype: dominance when AA = Aa in phenotype, A is dominant, a is recessive.irst we must appreciate that genes do not act in isolation.

Sulfa is short for sulfonomides which is a kind of antibiotic. Sulfonomides are not chemically related to sulpher or sulpher salts i.e. sulfates, sulfites-these dont not cause the same allergic reaction that you see with sulfonomide antibiotics. You should be careful with both kinds of drugs however as you can be allergic to both as I am. I get the same allergic reaction to both. Allergy to sulfa drugs is a popular term for related medications. Once allergic: sulfites, nickel and even tea laurel sulfate (found in soaps, shampoos, etc.), can cause irritation or an allergic response.
