Define Population size, inbreeding and genetic variation?

"Darwin proposed, and modern evolutionary biology affirms, that evolution is relies on variation in the characteristics of organisms." (Futuyma 1998, p. 231). Without genetic variation, populations would be unable to reply to either natural or artificial selection. Understanding the forces that influence genetic variation is significant to the basic science of evolutionary biology also to the applied sciences of animal and plant breeding and conservation biology.
