Wait I thought that was more of the idea that a slut retains genetic material from semen of her sexual partners and that the offspring is actually an amalgamation in part of the retained material along with the current partner's who is responsible for the insemination. Miscegenation is similar, but while disgusting and morally wrong.. doesn't explicitly result in inferior offspring? Assuming all partners are strong/healthy/intelligent subjects. Miscegenation seems as a different approach to reproduction from a biological/evolutionary stand point, similar to using a shotgun versus a rifle. A female who partners with many (healthy) subjects could produce slightly better offspring in a short time period, but carefully selecting a single partner yields far superior offspring over generations. Obviously either strategy is greatly impacted by the quality of the selected partners. I'm not a biologist, so I'm probably wrong. I don't think miscegenation is the correct term to mean the opposite of eugenics though..
