Five kingdoms & Seven levels

Explanation:

Robert H. Whittaker proposed five kingdom classical system for living organisms in 1969. These were: Kingdom Monera, Kingdom Protista, Kingdom Fungi, Kingdom Animalia, and Kingdom Plantae. His work was the improvement of earlier work conducted by Carl Linnaeus who proposed three kingdom classification system (Animalia, Plantae, and Protista).

Whittaker's system further categorized each kingdom to seven levels. These were: Kingdom → Phylum  →  Class  →   Order  →   Family →   Genus  →   Species. This categorization was based on similarities in organisms at different levels.

PS: The scientific name of each organism is the combination of genus and family name.

a unit of heredity that is transferred from a parent to offspring and is held to determine some characteristic of the offspring.
