outbreeding 

the opposite of inbreeding. outbreeding is a process of evolution. genetically different mates will produce offspring that inherits both parents' genes and is thus an advantage to offspring.

Cletus, the baptist hillbilly neocon: i done fucked my sis!
Phil: gross. your kids are probably going to die with both sets of the same genes.
Cletus: that's a liberal elite lie! everybody knows genes and outbreeding don't exist!
