User blog:American che/The Genetics Behind Phineas and Ferb (actually quite interesting)

We all assumed Jeremy and Candace get married, right? Then there's Xavier, Amanda, and Fred. Why do they look the way they look? Using Punnett squares, I've figured out why the kids look the way they do. (Punnett squares are a way to figure out what offspring will look like.)

First up is the hair color. Jeremy has blonde hair; Candace has orange, if you want to get technical. Using the Punnett squares, I deduced that Candace and Jeremy's Punnett square would look like this:



Their kids, Xavier, Fred, and Amanda, would look like this:



According to the Punnett square, Fred should have blonde or red hair. Either Dan and Swampy don't care, or they might have taken into account the fact that Candace or Jeremy could have a brown-haired gene somewhere. I doubt it.

Eye color coming soon!
