Immunology, phenotype first : How mutations have established new principles and pathways in immunology

This monograph deals with the impact of classical genetics in immunology, prov- ing examples of how large immunological questions were solved, and new fields opened to analysis through the study of phenotypes, either spontaneous or induced. As broad as biology has become, there are those who do not fully understand what the genetic approach is, and how it differs fundamentally from most of the methods available to natural scientists.
