21. We often think of natural selection as increasing the fitness of members of a species so that the individual members of that species are more likely to survive. However, sexual selection sometimes produces bright coloration which increases vulnerability to predators. The success of such sexual selection reminds us that

? The founder effect produces genetic drift.
? Sexual dimorphism is usually sex-linked.
? It is the survival of the individual, not the number of offspring produced, which determines reproductive success.
