Introduction
DNA is the basis of life and, therefore, has been widely used in almost all biological fields. Non-invasive DNA testing is a form of non-invasive testing that can identify DNA samples without harming the body. Recently, there has been constant controversy regarding the IQ tax for non-invasive DNA testing. On the one hand, some people think that this is the result of technological progress; on the other hand, they think that it will bring some negative impacts to society. This article will elaborate on this issue from four aspects.
Technical principles
The technical principle of non-invasive DNA testing is to detect fetal cell DNA in the maternal blood without the need to separate it from amniotic membrane or placenta samples. It usually uses second-generation sequencing technology, which can detect changes in DNA base sequences in human cells to provide people with a range of health information. Non-invasive DNA testing is actually a major advancement in technology. It can become a new method to prevent certain genetic diseases, and can also detect family diseases to prevent them in advance.
Detection Application
Non-invasive DNA testing can detect some common genetic diseases in advance, especially in the detection of fetal genetic diseases in early pregnancy, which has attracted more and more attention. Non-invasive DNA testing can also predict future diseases and provide preventive measures. This technology is also used in DNA gene editing, such as in developing vaccines, and in biological research, such as increasing crop yields or cleaving genes for breeding. In medicine, non-invasive DNA testing can assist clinical diagnosis and predict treatment effects.
IQ tax
However, the advent of non-invasive DNA testing has also raised concerns among some opponents. In particular, some traits related to DNA, such as IQ, height, etc., will become the new cradle of the theory of superiority between European, Japanese and Korean ethnic groups. Therefore, some people believe that non-invasive DNA testing will only increase people\’s anxiety and social instability. At the same time, this technology can be abused as a tool for IQ taxes in some countries.
Conclusion
Overall, non-invasive DNA testing is a form of technological advancement, and although it can provide more support for our lives, it still needs to be used with caution. Non-invasive DNA testing should not be abused as a DJIA (Eurasian Intelligence Assessment) or racial scoring tool. The scope of its use should be defined by laws and regulations. We must abide by the basic principles of ethics, human rights, equality and anti-discrimination. The advantage is that we can prevent diseases earlier, but the disadvantage is that we need to regulate the scope of testing use, prevent its negative impact, protect human rights and respect the privacy of personal information.
