What describes a gene?

• A. A type of crop
• B. A unit of heredity
• C. A method of farming
• D. A kind of fertilizer

Answer: (B)

A gene is best described as a unit of heredity, which is correct. Genes are segments of DNA that carry the instructions for the development, functioning, growth, and reproduction of organisms. They are the basic physical and functional units of heredity, determining traits that are passed from parents to offspring. This concept is fundamental in genetics, as genes are responsible for encoding proteins and influencing an organism's characteristics. The other options refer to concepts and items that are not related to genetics. A type of crop refers to a particular agricultural product, a method of farming describes techniques used to cultivate land or raise crops and livestock, and a kind of fertilizer is a substance that enriches soil to promote plant growth. None of these options pertain to the definition or function of a gene in biological terms.
