Question

Organisms in which of these following categories share least number of similarities?

• A. Species
• B. Genus
• C. Family
• D. Order

Answer 1

The correct option is D Order

Taxonomic hierarchy is the sequence of categories of organisms in an increasing or decreasing order.
Kingdom is the highest level of category, followed by phylum, class, order, family, genus and species.
The number of similarities between characters of organisms decreases from species to kingdom.
Hence, among species, genus, family and order, organisms in the category of order share the least number of similarities in their characters.
