摘要: The "sexy-sperm" hypothesis proposes that multiple-mating females have a selective advantage over single-mating because the former are fertilized by most competitive sperm and sons produce sperm. A deterministic genetical model of sexy-sperm process is described here. It assumes one locus influences ability second female mating behavior. conditions for competition to promote evolution multiple in very restrictive: there must be tight linkage between two loci, positive disequilibrium, no fitness cost associated with mating. Any trait (even behavior) can increase hitchhiking if it carries under control tightly linked positively selected locus. When costs mating, mechanism fails: tendency increases initially but eli...
