What is phenotype?

The phenotype is the set of traits that can be observed in an individual, for example, height, eye color, hair color, etc. It is the expression of the genotype in a given environment.

This means that the phenotype is determined by the identity of the alleles, which carry different positions on the chromosomes. Some phenotypes depend on multiple genes and are also influenced by environmental factors. For this reason, the identity of some alleles does not always predict the resulting phenotype.
