Which term describes the organism's complete genetic content?

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

Answer: (A)

The concept being tested is the organism’s complete genetic content. The correct term is genome, which refers to the entire set of genetic material in an organism or cell. This includes all genes plus the noncoding regions, regulatory sequences, and, in many organisms, the DNA found in organelles like mitochondria or chloroplasts. A genome is the full sequence of hereditary information that can be passed on to offspring. This differs from a gene, which is a specific unit of heredity that encodes a product or function. It also differs from an allele, which is a variant form of a particular gene. And it differs from genotype, which describes the particular combination of alleles an individual carries. So while a genotype or a set of alleles can reflect part of the genome, the genome is the complete content, not just individual components.
