White mother, white father, black baby

 
A white couple Dana and Hugh Clarke are shocked when Dana gives birth to a baby with African-American features. How do you explain this one? Is this even genetically possible for a white couple to have a black child naturally as Barbara Delinsky, author of ‘Family Tree' puts it?
So what would you do if this happened to you? Send your spouse packing or try to explore the genetic side of the story? And how do you even begin to convince your family and friends?
Well you gotta admit that this is one thought provoking book.
