1960 A. J. Cain & G. A. Harrison in Proc. Zool. Soc. 135 3 Following a suggestion made by Mr. H. K. Pusey, we shall refer to the arrangement by overall similarity, based on all available characters without any weighting as phenetic, since it employs all observable characters (including of course genetic data when available).
1971 Virology 45 357/2 To be useful, a classification of viruses..must be based on many characters, not few... This will give a classification based on the general resemblance of the phenotypic characters of the viruses (a ‘phenetic classification’).
1989 Nature 18 May 189/3 The phenetic resemblances of this hypodigm to H[omo] habilis are recognized.
2000 Proc. National Acad. Sci. U.S.A. 97 10684/2 This cladistic approach contrasts with the more traditional phenetic approach in which overall similarity (involving an aggregation of characters) is used to infer relationships.
