Somebody did "the incest math" over on Reddit
Jim and I were trying to gauge which is worse genetically when it comes to cousin fucking or aunt/nephew fucking, and the results are surprising. Cousins share about 12.5% of their genetic code, while an aunt and nephew would share 25%. But the Targaryen's are super, super inbred. This redditor analyzed the family tree and found that Dany and Jon would share a whopping 44% of their DNA. You're really playing Russian roulette with your blood lines at that point.
The top comments in that thread are a riot. "Incest is a ladder." "Chaos is a Targaryen family tree."
