Which term represents the hereditary information present in an animal?

• A. Phenome
• B. Proteome
• C. Genome
• D. Speciation

Answer: (C)

Hereditary information is the complete set of instructions an organism inherits, stored in its genome. The genome includes all genetic material—genes and the regulatory elements that control when and how those genes are expressed—which together act as the blueprint passed from parent to offspring. This genetic blueprint determines inherited traits and is the source of heredity. The other terms describe different things. The phenome refers to the full range of observable traits produced by gene expression and environmental influence, not the inherited blueprint itself. The proteome is the full set of proteins that are actually produced, reflecting gene expression at a given time rather than the inherited information. Speciation is the evolutionary process by which new species arise, not a description of the information inside an individual.
