Text 1: Geneticist Park argues that direct-to-consumer DNA tests offer real value. Customers learn about ancestral origins, health risks, and family connections at a fraction of clinical costs; millions of people have engaged with their own biology in ways earlier generations could not imagine.
Text 2: Geneticist Singh accepts that direct-to-consumer tests deliver genuine information but argues that the format frequently misleads. Risk variants are reported without the clinical context that would interpret them; ancestry results obscure the statistical estimates behind their colorful pie charts; data privacy practices have repeatedly fallen short. The information is real; the presentation often is not.
Both authors would most likely agree that
- A
consumers should be barred from learning anything about their genetics.
- B
such tests provide no useful information whatsoever.
- Ccheck_circle
direct-to-consumer DNA tests provide real biological information.
- D
ancestry estimates are perfectly precise.
Explanation
Both accept that the tests provide real biological information; they differ on presentation and interpretation. A is shared. B, C, and D contradict at least one author.
