Genotype

In biology, the students learn the difference between the genotype and the phenotype.

In biology, it is important to distinguish phenotype from genotype.

Boceprevir is only expected to be effective against one variety of hepatitis C, known as genotype 1. It's the most prevalent form of the disease in the Americas, Europe, and East Asia, but represents only a minority of cases in Africa, the Middle East, and South Asia.

Biological sex has at least as much to do with phenotype as with genotype.
