The chances of Stan and Kyle having an mpreg baby with red hair are pretty low. Though negniahn points out to me that both Stan's Uncle Jimbo and Aunt Flo have red hair, I would argue that Jimbo's hair is more brownish than not. Also, Aunt Flo is an old woman so she's probably dyeing her hair. I have pointed out that Aunt Flo is actually a personification of Stan's mother's period, to which negniahn has argued that "Kyle is the personification of everyone's period," which I guess is a fair point. But even if Aunt Flo's hair was actually red, she's Stan's great aunt (or maybe great-great aunt?), which means the genetic link between them isn't that close. So, sure, it's possible that Stan and Kyle's mpreg baby might have red hair, but, look, probably not.
