Genetics is a highly unpredictable thing. Sometimes it seems to seek to endow offspring with all the best or worst traits available. Hence the characteristic lament of parents who discover that instead of their dream girl, they have a rough-and-tumble boy, or that their long-awaited manly heir is actually a doe-eyed female. Or the kid simply is the opposite of what they want in talent or personality. Needless to say, this usually does not result in happy-go-lucky familial relations.
