For the last 40 years, very important contribution has made by the area of molecular genetics inthe field of biology which includes: conservation biology, population genetics and systematics.*From those days, development of various types of techniques are helping us in finding anddescribing measure of genetic varieties. However, protein electrophoresis is the most importantamong these early techniques. With the emergence of protein electrophoresis in the 1960s, theexamination ability of variations in genetics in wild populations or natural leads to an era in thearea of genetic. It became possible for the researchers to examine theories and predictionsregarding both the levels and sustaining genetic variation for natural inhabitants.As a result of the data about the study of these early proteins, many debates are fueled due to thiswhich are still going on (e.g. the neutralist/selectionist debate). In order to shape population aswell species, first it is important for us to understand from the data about their roles. Though theprocess of protein electrophoresis is very helpful in various cases, but it also has few limitations.Perhaps, the most recognized is that among all the variations existing in individuals thistechnique is able to recognize about one-third, that is because of the dismissal of the genetic codeand the technique’s power of resolving. Numerous methods have been searched by manyresearchers for way which observed the high variations carried at the level of nucleotide due tothe limitations. Almost a decade later the capability in determining the real base pair order ofgenetic code itself, via sequencing of DNA, showed the way to further progress in moleculargenetics and the research in going on for variation in genetics. However, just after thedevelopment of polymerase chain reaction (PCR) in the middle of the 1980, the studies based onsequence became universal.Actually, today various protocols and methods depend largely on the technique of PCR. Itbecome possible for the researchers to avoid the limitations connected with the method of protein
