On the other hand, a phenotype is how that trait expresses physically, a characteristic, a visible description of your physical features, including height, eye color, overall health, history of diseases, the ability to gain or lose weight fast, what type of food you like, what you enjoy and what you hate. 

In general, your phenotype is influenced by genotype and the circumstances and conditions you live in.
