I've just had the opposite happen in respect to cute vs fugly. Heath was a rather handsome baby, toddler, child and teen. Then, he grew up. Get a load of that nose. His brother, who is a genetic clone btw, turned out incredibly handsome.
And I've had a baby just born to a father with D-black/R-black and a mother with D-red/R-red hair. The boy has black eyebrows and blonde hair. His new little sister (different mother, D-black/R-black) has red hair and black eyebrows.
And my mail lady miraculously switched from blonde to black, without changing her thumbnail.
I can't begin to tell you how PLEASED I am to have installed this *expletive deleted* patch. At least now my vampires won't have the Grand Vamp hair.
(/sarcastic tone) I'll be uninstalling/reinstalling pets without the patch tonight...
