Genetic Linkage

I’m a Geneticist. A DNA Test Uncovered a Half-sister and Sparked Painful Questions

In her new book, "Inheritance: A Memoir of Genealogy, Paternity, and Love," Genealogy, Paternity, and Love," author Dani Shapiro is speaking for tens of thousands of us who are discovering that we are "NPE." Not Parent Expected.

So thank you Dani. Here's a short version of my story, as many of us face the deluge of new cousins coming in from the holiday wave of DNA tests.
