Question

As we go from species to kingdom in a taxonomic hierarchy, the number of common characteristics:

• A. Remain the same.
• B. May increase or decrease.
• C. Will decrease.
• D. Will increase.

Answer 1

The correct option is C Will decrease.

All the members of a taxonomic category possess some similar characters which are different from those of others. The placement of individuals or organisms in species, genus, family, order, class and phylum are determined by their specific similar characters and relationships.
Maximum similarity occurs in species which is also the lowest category in the hierarchy of categories. Similarity of characters decreases with the ascent in hierarchy.
