Gene

1. Identify the trait mentioned. 2. Recall that the trait is controlled by genetic information. 3. State that a gene is a segment of DNA on a chromosome. 4. Add that different genes control different traits. 5. Give one plant or human example.

A chromosome sketch with one marked gene segment helps students remember that a gene is a part, not the whole structure.

A common wrong answer is to call the gene the whole chromosome. The chromosome is bigger and carries many genes.

A gene is a small functional part of DNA on a chromosome that carries information for a trait.

A gene is a small functional part of DNA on a chromosome that carries information for a trait. A gene is a segment of DNA on a chromosome; many genes together make up a chromosome. In pea plants, one gene can control stem height, while another gene can control seed shape. In humans, genes help decide features such as blood group and eye colour pattern.

A gene acts like an instruction unit inside the hereditary material. It does not work alone as a whole chromosome; instead, it is one useful section that helps decide a specific feature such as seed shape, flower colour, or height pattern. Different genes influence different traits, which is why parents pass information to children in an organised way. A gene is a segment of DNA on a chromosome; many genes together make up a chromosome. If a pea plant has one gene for tallness and another for seed shape, each gene influences a different feature. The height gene helps decide whether the plant grows tall or short, while another gene decides a different trait. Define a gene, state its location, or explain why genes are called units of heredity. A common wrong answer is to call the gene the whole chromosome. The chromosome is bigger and carries many genes.
