Model Answer
A gene is a functional unit of DNA on a chromosome that carries information for inheritance of a specific trait from parents to offspring.
Source: Chapter 8, Section 8.2 Heredity; Chapter 7, Section 7.1

Explanation
- Examiners expect you to link gene → DNA → trait/inheritance in one line.
- The passage states that chromosomes contain DNA, which is the "information source" for making proteins and inheriting features — a gene is the specific unit of that information for one trait.
- Avoid vague answers like "genes are in cells." Always mention DNA, chromosome, and trait/inheritance for full credit.
