An imaginative inquiry that attempts to unravel and understand the social implications of the medical revolution known as genetic ancestry testing.

A young woman tells her father, himself a geneticist, that she and her sister have undergone a genetic ancestry test despite his many warnings against it. Sensing his daughter’s apprehension, he tells her how, through his work, he came to understand the significance of genetics in identity research.
