Inaccuracy Of Genetic Testing

Decent Essays

Unfortunately, genetic testing tends towards being inaccurate with specific empirical data missing, and the common tool for its analysis appears to be nothing more than fictionalized scenarios, accompanied by varying interpretations and applications of test results. (B-232) The more common ancestry tests rely on short stretches of DNA in mitochondria, the cell-powering organelles. These mitochondria are inherited through the mother, or on the Y chromosome which is passed down from father to son. Mitochondria and Y chromosomes developed specific changes to them as people migrated around and across the world, and tied them to different populations, but charting an unbroken line along ‘uniparental markers’ (the paternal or maternal line) is …show more content…

If membership is called into question, it can become political and even messy. Kimberly TallBear, professor of American Indian studies at Arizona State University, claims that the inaccuracy of genetic testing can result in some tribal members not having the “correct” markers, but some with either little, or no connections to the tribe will have them. (#2, p.2) Currently, tribal ancestry tests are not being recognized by most tribes.
Genetics, the law, and society converge with little understanding of the potential implications of DNA ancestry testing and its statistical limitations. Understanding is critical for advocating consumer rights and protection relating to utility of DNA results and the appropriate social meaning. Scientists often criticize genomic tests’ speculative nature and the ethnic ancestry testing because they make more claims than they can deliver. DNA material could be too diluted to provide accuracy, or the margin of error could cause results to show ancestry from one continent that doesn’t really exist. (1. …show more content…

For those who are truly disadvantaged because of their race, would this testing undermine the programs meant to help, or compensate them?? In 2003, the Supreme Court decided the right to use race as a factor in college admissions. Lester Monts, University of Michigan provost for student affairs, offers, “If someone appears to be white and then finds out they are not, they haven’t experienced the kinds of things that affirmative action is supposed to remedy”. Yet, most universities simply rely on students’ self-description of racial preferences. There is a real dilemma about how to apply DNA results on applications and employment forms. Some go as far as checking all the relevant boxes in hopes that they will realize some benefit.
