We turn to our "Gma" cover really interesting one. An Ohio family suing their fertility clinic claiming a DNA test revealed their 24-year-old daughter is not biologically related to her father. ABC's Stephanie Ramos is here with more on this. Good morning, Stephanie. Reporter: Good morning. The couple in this case says it was an innocent gift. Given to them by their adult daughter Rebecca last Christmas. An at home DNA kit. But the results a month later showed Rebecca's biological father was not the man who How did this happen? How could something like this have happened? Who is she biologically related to?
