Question

Quizplus · Accepted Answer

Disease risk can vary depending on the geographic origin of one's ancestors. For example, people of Ashkenazi Jewish descent are more likely to be carriers of a number of autosomal-recessive diseases. We cannot accurately identify a person's race from his or her DNA, and knowing ethnicity does not accurately predict Huntington disease risk. Natural selection decreases genetic diversity.
