WebFitness is result of the individual properties and how well the individual can get along in the environment that it finds itself, in comparison to other individuals who might be competing for resources in that environment. There is no concrete definition of fitness. WebA genotype's fitness depends on the environment in which the organism lives. Fitness is a handy concept because it lumps everything that matters to natural selection (survival, mate-finding, reproduction) into one idea. The fittest individual is not necessarily the strongest, fastest, or biggest.
