You wait for your family to respond to your impromptu technical explanation on the genetic analysis you’re working on and your uncle is the first to comment.
“Genetics is crazy like that. This one time, we had a family that lived down the street and the mom, the dad, the grandparents, even all of the children were all red heads. Even the cat was ginger. Then one winter, the mother gives birth to a daughter with blonde hair. How crazy is that?! Then one day we found out she was cheating. Now that was a messy divorce. That girl was just like her sisters, I think she was his.”
Doesn’t seem like anything stuck, what do you do?
