The functional unit of heredity is what?

The functional unit of heredity is what?

• A. Gene
• B. Chromosome
• C. Allele
• D. Genome

Answer: (A)

Genes are the basic units of heredity because they carry the specific information that guides the development and functioning of organisms and can be passed from parents to offspring. A gene is a particular sequence of DNA (or RNA in some organisms) that directs the synthesis of a product, typically a protein or a functional RNA, which in turn influences a trait. A chromosome, while important, is the larger structure that houses many genes. An allele is a variant form of a gene that can lead to different traits. A genome is the complete set of an organism’s genetic material. So the gene is the functional unit of heredity because it directly carries the information that leads to inherited traits.
