The Popularity of DNA Tests
DNA testing has a lot of uses. For example, it can be used to find out a person's biological parents with much greater certainty than winning big at Quatro with its free spins. Likewise, it can be used to connect criminals with criminal cases, which is not just useful for catching criminals but also useful for freeing people imprisoned because of wrongful convictions. With that said, DNA testing is also proving useful for people of all zodiac signs who are interested in learning more about their genetic background, which is something that has produced some rather amusing results here and there because as it turns out, people don't stay in one place for the whole of human history.
Why Are DNA Tests Causing Some People to Become Upset?
First and foremost, there are a lot of white supremacists who are getting upset by DNA testing because the chances of it producing results that are unacceptable for them are much higher than the chances of winning big at Quatro with its free spins. In short, white supremacists tend to operate on the "one drop" rule, which comes from a rather unpleasant part of U.S. history when even a single sub-Saharan-African ancestor meant that someone would be considered black. As a result, some white supremacists have been using DNA testing to prove their genetic credentials. Unfortunately for them, human populations have been mixing with one another since time immemorial, which is why their DNA tests sometimes produce results showing partial descent from either sub-Saharan Africans or some other ethnic minority that they hate. One excellent example was a white supremacist named Craig Cobb, who went into outright denial when presented with the fact that he had 14 percent sub-Saharan-African heritage on a British talk show.
Of course, there are also cases when people will become upset because of less amusing reasons as well. For example, when someone finds out that their child isn't theirs in a biological sense, that tends to be rather devastating. Likewise, the reverse situation isn't that much better because the child has had one of their fundamental assumptions about the world knocked out from under them, which tends to make most people more than a little bit uncertain. Certainly, there are some people who come out of such experiences with even stronger bonds because they know that they love one another because of choice rather than some vague notion of biological obligation. However, people of all zodiac signs tend to experience a great deal of emotional pain in such cases even if they manage to come out alright in the end.
How Much Trust Should People Put in DNA Testing?
With that said, interested individuals might want to be careful about putting too much trust in DNA testing under certain circumstances. For example, DNA tests tend to be very accurate about whether someone is someone else's child or not because the chances of an error are very low. However, when it comes to figuring out someone's heritage from various ethnic groups, that can be much more complicated.
After all, DNA testing is supposed to find out a person's heritage based on the presence of variations in their genome that are associated with particular racial and ethnic groups. The problem is that the correlation between these variations and various groups is far from being perfect, not least because some of them can exist in more than one such group. As a result, it is not unknown for DNA testing intended to determine a person's heritage to come up with false positives. On top of this, the companies carrying out the DNA testing are working with limited databases of samples that can be used as references, meaning that they have limited information on the kinds of variations that are associated with various racial and ethnic groups.
Summed up, DNA testing for the purpose of determining one's heritage can be rather interesting, but the chances of error mean that people shouldn't put too much stock into it. The chances aren't as bad as winning big at Quatro with its free spins, but they are still significant enough that interested individuals shouldn't change their fundamental assumptions about who they are based on them. This is particularly true because the definition of racial and ethnic groups is much more social than biological in nature anyways, meaning that DNA might not be the best place for people of all zodiac signs to start looking if they are interested in their heritage. Instead, interested individuals might want to look into genealogical records if they are interested in that sort of thing. Granted, that is not always possible because genealogical records are not complete, but if people want to be optimistic, they can always interpret that to mean that they will be the ones to determine who they are in the most fundamental sense rather than let it be determined for them by their ancestors.
