About this talk

While searching for a kidney donor, Karen Keegan stumbled upon a mystery. After undergoing genetic testing, it turned out that some of her cells had a completely different set of genes from the others. And this second set of genes belonged to her twin sister- who had never been born. How did this happen? Kayla Mandel Sheets explores the condition known as chimerism.
