Molecular Biology and Genetics

Genetics is the branch of biology concerned with the study of genes and their role in inheritance – the manner in which certain traits are passed down from generation to generation.  There are various degrees of genetics: Transmissible genetics, deals with studying how the hereditary traits are passed from parent to progeny. Here the transmission of traits is studied at a single organism level. Molecular genetics studies the chemical nature and function of the gene itself and evaluates how genes encode the genetic information which is replicated and then used by the organism in the form of protein. Same gene across different species, individuals and types of organism is also studied. Population genetics studies the makeup of the population in one species, and deals with genetic differences within and between populations with large number of individuals to study the variations in the species or gene pool.
