The research attempts to authenticate a proposal on the presence of a chromosomal lineage that was found in men across the Asian region (Zerjal, et al., 2003). The proposal holds that there was a phase during the time of the Mongols which indicates a behavior that is far from natural and can be concluded to be selective.
The research hardly provides any background information that can be interpreted to be the rationale of the research. There is a large amount of information present on the role of the subject chromosomes.
The research barely presents a justification as the researchers mentioned the potential role of the subject chromosome. The justification can be found in the speculation that a relationship exists between resistance to illnesses and the subject chromosome.
The paper hinges on the fact that DNA variations are generally attributable to a combination of processes constituting natural selection as well as neutral processes. The paper suggests that each of these two processes works in a contradictory nature to the other.
A study was performed to probe into the degree to which Genghis Khan’s days may have had an influence upon men of his native region for the next one thousand years.
The research initially made use of the survey technique in which variations in the DNA of men across Asia were recorded. Once the data had been recorded, the BATWING program was used to speculate upon the next one thousand years where each generation constitutes thirty years. Further on, the research made use of probability to determine the position of selection and neutral processes about the lineage. It is essential to mention at this point that the research may have made use of the appropriate software in the research but there was no sign of any specific or sophisticated methods of probability at any point in the research (Zerjal, et al., 2003).
The main hypothesis of the research was that a small yet significant share of the current Asian population in men owes its lineage to a particular male line and that this phenomenon has occurred as a result of selection in contradiction to neutral processes.
The research findings showed that nearly 0.8% of the current world population in men owes its lineage to a single DNA variation (Zerjal, et al., 2003). The research continued by deriving conclusion upon conclusion without taking a stance on any particular direction. With a rambling nature of a conclusion, the paper comes to a close leaving the reader in a state in which the absence of research questions is strongly felt.
The research results served to agree with the hypothesis considered by the researchers. However, it is essential to note that a strong need was felt during the study of the paper for advanced analysis tools. The research became almost predictable during its evaluation and it would have been feasible if the researchers had made use of an exploratory approach.
While the research does not constitute any particular conclusion, one can surmise that the research converges on Genghis Khan’s role in the similarities found across the male population of the South Western regions of China. The research comes to a close after having established the existence of a selection in the days following Genghis Khan’s (Zerjal, et al., 2003).
The discussion is more than sufficient in the interpretation of the results. It is perhaps the one area of the research where no shortfalls are present and an exceptional and highly credible result has been presented.
