Danielle Teuscher decided to give DNA tests as presents last Christmas to her father, close friends and 5-year-old daughter, joining the growing number of people taking advantage of low-cost, accessible genetic testing.
But the 23andMe test produced an unexpected result. Ms. Teuscher, 30, a nanny in Portland, Ore., said she unintentionally discovered the identity of the sperm donor she had used to conceive her young child.
The mother of the donor was identified on her daughter’s test results as her grandmother. Excited and curious, Ms. Teuscher decided to reach out.
