Question

Phenetic classification of organisms is based on

• A. Dendrogram based on DNA characteristics.
• B. Sexual characteristics.
• C. Observable characteristics of existing organisms.
• D. The ancestral lineage of existing organisms.

Answer 1

The correct option is C Observable characteristics of existing organisms.

In biology, phenetics is an attempt to classify organisms based on overall similarity, usually by morphology or other observable traits, regardless of their phylogeny or evolutionary relation. It includes various forms of clustering and organisation. Phenetic classification of organisms is based on measurable similarities and differences rather than genetic makeup and evolutionary descent.

Thus, the correct answer is option C.
