Phenetic classification is based on:
- The ancestral lineage of existing organisms
- Observable characteristics of existing organisms
- Dendrograms based on DNA characteristics
- Sexual characteristics
The Correct Option is B
Solution and Explanation
Phenetic classification, also known as phenetics, is based on observable characteristics or phenotypic traits of existing organisms. It involves grouping organisms together based on overall similarity in characteristics without necessarily considering their evolutionary history or ancestry.
So, the correct option is (B): Observable characteristics of existing organisms

Biological Classification
The process of grouping living organisms into categories is called biological classification. The most modern 5-kingdom classification was put ahead by an eminent scientist R.H.Whittaker. The five-kingdom classification is based on the criteria like cell structure, mode of nutrition, body form, and reproduction. One of the most important characteristics of this system is that it follows the evolutionary sequence of living organisms. The organisms are classified into distinct taxa or levels like Kingdom, Phylum, Division, Class, Order, Family, Genus, and Species. The 5 kingdoms are as follows:
