Genosystematics

Genosystematics may be defined as the science of the variety of molecular genetic regulatory systems (MGRS) and semantids of organisms and their molecular genotypes. This science integrates the relevant knowledge needed to construct a comprehensive system of organisms. The term genosystematics [339] seldom occurs in the literature. However, it appears to be more convenient than, for example, ‘DNA systematics’ or ‘molecular systematics’. The former is too narrow in its application and, as its name shows, leaves two large groups of semantids (the RNAs and the proteins, and MGRS) outside the frame of reference. Conversely, the latter term is too wide and includes the evidence on episemantids, i.e. the subject of chemosystematics. In addition, neither term adequately reflects the difference between the object of genosystematics (genotype, genome of organisms) and that of phenosystematics.
