Sorry, your blog cannot share posts by email. However, despite a thorough botanical classification of taxa in the genus, the molecular taxonomy of endemic species from Central Asia is poorly understood. Studies of its molecular taxonomy have shown that this genus is well-classified and suggest a separation of 226 species into two subgenera and 17 sections. Molecular techniques in the field of biology have helped to establish genetic relationship between the members of different taxonomic categories. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. The Code is meant to guide, only the nomenclature of animals, while leaving zoologists freedom in, In other words, whether a species itself is or is not a recognized entity is a, s objective decision, but what name should be applied to it is not. only the nomenclature of animals, while leaving zoologists freedom inclassifying new taxa. 2.4.

According to Sokal and Sneath, numerical taxonomy has the following advantages over conventional taxonomy: a. Molecular genetic methods provide taxonomy with a powerful tool to identify or describe species, as they apply to all organisms and offer quantifiable characters. When trying to measure degrees of genetic relationship it is very important to look for the genetic material they are composed of and this is when molecular taxonomy comes into play.
