Computer simulation of genetic mechanism !!
Computer simulation is the discipline of designing a model of an actual or theoretical physical/biological system, executing the model on a digital computer, and analyzing the execution output. Simulation embodies the principle of ``learning by doing'' --- to learn about the system we must first build a model of some sort and then operate the model. The use of simulation is an activity that is as natural as a child who role plays. Children understand the world around them by simulating (with toys and figurines) most of their interactions with other people, animals and objects. As adults, we lose some of this childlike behavior but recapture it later on through computer simulation. To understand reality and all of its complexity, we must build artificial objects and dynamically act out roles with them. Computer simulation is the electronic equivalent of this type of role playing and it serves to drive synthetic environments and virtual worlds. Within the overall task of simulation, there are three primary sub-fields: model design, model execution and model analysis
Simulation models have become important tools in Bioinformatics studies. There are many reasons for this, but we emphasize three of the more important:
(1) they enable exploration of hypotheses, and as such, have become invaluable means to guide research;
(2) they are unique approaches to integrate (in the literal term of the word) biological knowledge, in the form of experimental results; and
(3) they enable connecting biology with other fields of study ranging from physiology to genomics;
This blog, and this software list, is intended to guide the potential user of simulation models.
It is not, in any way, meant to be comprehensive on the very diverse simulation tools that already exist, but focuses on mechanistic, dynamic models. Similarly, it is not meant to provide any coverage of the breadth of applications; however, for interested readers, we provide references to use as a possible starting point.
Simulation models are meant to answer questions which scientists have in a dynamic, quantitative, and often, a pictorial way. Much of the bioinformatics research and its applications, in particular, involve a large number of components, actors, and factors. Assembling these in a coherent framework may seem a daunting task, especially for beginners, and can lead to confusion, even for experienced scientists, especially if the objectives of such an exercise are not well defined. Followings are the list of tools bioinformatician may use to analyze and provide answers to complex biological mechanisms and related problems.

Comments
Thanks for such a useful list of tool for simulation studies. I guess you forgot to add RSVSim: an R/Bioconductor package for the simulation of structural variations ( https://www.bioconductor.org/packages/release/bioc/html/RSVSim.html ) in the list.
Thanks for the list. I came across GPOPSIM: a simulation tool for whole-genome genetic data ( http://bmcgenet.biomedcentral.com/articles/10.1186/s12863-015-0173-4 , which seems the best for be a useful tool for the methodological and theoretical studies in the population and quantitative genetics and breeding.
