2024 jamb biology question: A character shown by an organism is due to the effects

• Topic: Protozoa / Unicellular Organisms / Cell Biology

Question: 

A character shown by an organism is due to the effects of (A) hormones only (B) genes only (C) genes and environment (D) environment only

Answer:

Topic: Genetics / Heredity and Environment

Explanation: What an organism looks like and how it functions (its characteristics or traits, called the phenotype) is almost always a result of an interaction between its genetic makeup (its genes, inherited from parents) and the environment it lives in. Genes provide the blueprint or potential, but environmental factors (like diet, temperature, sunlight, upbringing) influence how those genes are expressed. For example, you might inherit genes for being tall, but if you don’t get enough nutrition (environment), you might not reach your full potential height. It’s rarely just one or the other.

Correct Answer: (C) genes and environment
