According to this really cool site I found this morning, my son looks 17% more like me than he does like my ex. (I made my son give me a high-five for dominant genes after I found out.)

This is really fun! You basically upload a photo of the child, mother, and father, and their technology scans your faces to determine who the child more resembles. I tried it a few times, with different pictures, and the results were the same each time. I don’t know what their criteria is or what features they evaluate, but I’m sure it’s discussed somewhere on the site. (I was too lazy to look for it / too busy celebrating the triumph of my genes.)
