Abstract

Taxonomical awareness on species, the intraspecific and interspecific relations etc, are the necessary pre requisites in different fields of applied biology, such as in biological resources management and conservation, in mariculture ventures, in pest/pathogen control and identification, etc. Generally, there are two contexts in which significant problems arise in species identification, where the molecular approaches are applicable. The first concerns the very fundamentals of taxonomy, in identifying the species, the phylogenetic status and the identification at subspecies and hybrids level. The second concerns to ecologists are the issue of identifying the species sex, or identity of individuals under circumstances where simple morphology cannot be relied upon. Biodiversity studies require species level analyses to assess the community structures. In conventional taxonomic practice, organisms were classified based on their fine morphological characters, comparative osteology, etc., which are more time consuming, laborious and expensive. Moreover, in some situations, morphological variation arises due to the environmental factors rather than genetic causes and is therefore not heritable. In this context, classification of organisms based on the molecular variations using the modern molecular tools has got a wide acceptance globally.
