Answer: Phenotype
Explanation:
The phenotype is the set of physical characteristics of an individual, that make it different from other individuals and are evident to the eye.
While the genes inherited from the parents determine the genotype of the individual, that's not enough to fully determine how it will look when it develops, as the ambient where it will grow takes a great part of it. Those factors are called epigenetics.
How an individual will look, its phenotype, is a result of its genes and the epigenetic factors.
