Phenotype

/ˈfiːnətaɪp/
The set of observable physical, biochemical, and behavioural characteristics of an organism, resulting from the interaction of its genotype with the environment.

✍️ Usage in a UPSC answer

Public-health policy must reckon with the fact that the burden of non-communicable disease is not written in the genotype alone; the diabetic and hypertensive phenotype increasingly visible across urban India is the joint product of inherited predisposition and an environment of sedentary work, processed diets and chronic stress, which is precisely why nutrition and lifestyle interventions, not genetics, hold the key to prevention.

🔡 Root

Greek phainein = to show, appear; typos = mark, type; coined by Wilhelm Johannsen in 1911

📜 Etymology

From Greek phainein ("to show, appear") + typos ("mark, type"); coined by Danish botanist Wilhelm Johannsen in 1911.

🧠 Memory Hook

"PHENO" echoes "phenomenon" — both from Greek phainein, "to appear." A phenotype is the genome made into a visible PHENOMENON, the part of you that actually APPEARS (skin, height, behaviour), as opposed to the hidden genotype.
