A convenient way to illustrate this is to plot a curve tha...

Short Tandem Repeat (STR) markers are best choice for the genetic structure assessment of a population due to codominant inheritance, high polymorphism, mutation rate and ease of use [1,2]. Polymorphic STR loci have become useful tool for DNA analysis and typing for human identification and paternity testing for forensic purposes in most of the forensic laboratories in the world [3,4]. Determin...
