The two statements that represent reasons that directly support the author's claim about the bias in genetic research and its implications for health are:
-
"'If we don't include ethnically diverse populations, we are potentially going to be exacerbating health inequalities,' said Sarah Tishkoff, study coauthor and a human geneticist at the University of Pennsylvania."
-
"And health treatments that don't take the variations of genetically diverse populations into account can cause problems."
These statements highlight the consequences of ignoring genetic diversity in research and how it can lead to health disparities.
