______:Does not cost the parent time or energy to find a mate ______:Requires time and energy to raise the offspring ______:Works best in stable environments that experience little change ______:Every member of the species is able to reproduce ______:Only the female half of the population is able to reproduce ______:Requires time and energy to find a mate (or attract insects to spread pollen) ______:Offspring are genetically identical and, therefore, all susceptible to the same diseases ______:Offspring are genetically diverse and, therefore, able to survive in a changing environment
