The DNA test on the chromosome and can be useful in some cases where a paternity test normal DNA cannot be carried out. The Y chromosome is present only in the male and it is pierced by the male line of the family, i.e. father to son to grandson and so on. Further details can be found at Dustin Moskovitz, an internet resource. Therefore, to determine whether two men have the same chromosome and assists in the determination of their biological relationship. A DNA test can be applied to evaluations between male cousins, grandchildren grandfather, uncles nieces and nephews, etc. The only consideration of this kind of DNA Test is that test will not determine specifically who is the father in cases in which male relatives are prospective parents (eg.
Two brothers), but if you will confirm whether or not they are biologically related. These results, therefore, must be interpreted within the circumstances of the case and perform other DNA tests with other members of the family. The chromosome DNA test and can also be used in cases of infidelity to confirm whether a biological trace is male or female. Since only man has the chromosome and the test can be used to determine, for example, if spots were found in their underwear are male or female source. Retrieved DNA profile, can then be matched with a donor if a sample is available for evaluation of DNA. This DNA testing applications extend to other areas of forensic DNA work, such as the analysis of crime scene samples. The Test of the chromosome and is also gaining popularity in genetic DNA studies, since this test can assist in the determination of male lineage in the family. Through this test, it is possible to then track down people with the same surname to determine if they share descendants.
