What's That Advantage

a: Homosexuality ~
b: sickle-cell anemia

What: "Perhaps homosexuality is like sickle-cell anemia, and it provides a great (though as yet unidentified) benefit to heterosexuals who carry the gene without expressing it fully. "Very unlikely," writes Ewald. "These defenses tend to involve grossly defective proteins that inhibit pathogens more than they negatively affect the person carrying the trait. No one has yet identified any such defective proteins in gay men." Strike one."
