The Basics of Forensic DNA Testing and the Ethics Behind It Although DNA testing is something that is used primarily by scientists who can use and interpret DNA and the results of testing processes, DNA in recent years has become a fantastic tool for use in forensic science. Testing Different Relationships with DNA Testing DNA profiling technology has come a long way in the last few decades, and it is now possible to identify a number of difference biological relationships between any given person. Through using slightly more in-depth matching processes than with traditional DNA paternity tests, the wider testing methods available are nevertheless accurate enough to determine whether or not there is some biological connection to establish relationships Using DNA Testing DNA testing is by far the most effective and accurate means by which a biological relationship can be said to exist between one person and another. Whether that be through traditional paternity testing or alternatively testing some more distant relationship (usually in order to determine paternity), such as avuncular testing or grandparentage testing, there are a number of significant reasons for using DNA testing where disputes or potential discrepancies arise. Applications of Y Chromosome testing The Y chromosome DNA test can be useful in certain cases where a normal DNA paternity test cannot be performed. The Y chromosome is present only in males and passed on through the male lineage of a family, that is from father to son to the grandson and so forth. Therefore determining whether two males have the same Y chromosome will assist in determining their biological relationship. The DNA test can be applied for testing between male cousins, grandfather and grandson, uncles and nephews etc.
