Q.The taxonomy which involves the similarities and dissimilarities among the immune system of different taxa is termed as ________.

Serotaxonomy (also called immunotaxonomy, or systematic serology) originated towards the end of the 20th century alongside the discovery of serological reactions and the growth of immunology as a discipline. It classifies very similar plants using differences in the PROTEINS they contain - Smith (1976) defined it as 'the study of the origins and properties of antisera.' Practically, it determines the degree of similarity between species, genera and families by comparing the reactions of ANTIGENS from various plant taxa against ANTIBODIES raised against the antigen of one known taxon - the more closely two taxa react, the more similar their proteins, and by extension the closer their relationship. Example: the reassignment of Phaseolus aureus and *P. mu …
