In somewhat relevant news. One of my pet peeves, when I read fiction or see art that includes the results of our fetish, is that people often don’t know how genetics work.
Even in professionally produced works the kids always end up looking exactly like one parent or the other. If Beast and Cecilia Reyes have kids genetics say their traits should draw from his original form; A white male. *
However writers often enjoy giving them exactly two children. One that looks like Mom and the other that looks like Dad. As seen here in X-men: The End.
Usually they go so far as to make them little copies. The son always takes after the father while the daughter takes after the mother. This often comes up in the form of fraternal twins.
It’s a cute little “Just like mommy, Just like daddy.” Cliche but it gets annoying.
But sometimes Genetics say FUCK YOU.
* I had a discussion with several people about this and they agreed. But let the Nerding commence.
