how reproductively successful an organism is in its environment
|
Detailed explanation-1: -To an evolutionary biologist, fitness simply means reproductive success and reflects how well an organism is adapted to its environment.
Detailed explanation-2: -In the crudest terms, fitness involves the ability of organisms-or, more rarely, populations or species-to survive and reproduce in the environment in which they find themselves 6–9. The consequence of this survival and reproduction is that organisms contribute genes to the next generation.
Detailed explanation-3: -Fitness is a measure of how well organisms survive and reproduce, with emphasis on “reproduce.” Officially, fitness is defined as the number of offspring that organisms with a particular genotype or phenotype leave behind, on average, as compared to others in the population.
Detailed explanation-4: -Biological fitness is defined as an organism’s ability to pass its genetic material to its offspring. Species that are more “fit” can pass on their genes and ensure their survival. Fitness evolution is when a species biological fitness can change from one generation to another.
Detailed explanation-5: -Reproductive fitness reflects the ability of individuals to pass on their genes to subsequent generations. Fitness traits, also referred to as life-history traits, include measures of fertility and mortality and are complex phenotypes that are direct targets of Darwinian selection.
