Phenetic classification of organisms is based on:

Step-by-step solution

Phenetics is a form of numerical systematics in which organisms are grouped based upon the total or relative number of shared characteristics (based on observable similarities and differences between taxa) while phylogenetics is the systematic study of organism relationships based on evolutionary similarities and differences. Related Theory Cladistics considers both phenetics and phylogenetics. the accuracy ofcladistics is greater than the accuracy of phenetics in classifying organisms.
