The quality of being suitable to fulfill a particular role or task
he had a year in which to establish his fitness for the office
An organism's ability to survive and reproduce in a particular environment
if sharp teeth increase fitness, then genes causing teeth to be sharp will increase in frequency
the quality of being suitable; "they had to prove their fitness for the position"
good physical condition; being in shape or in condition
seaworthiness: fitness to traverse the seas
Fitness (often denoted in population genetics models) is a central idea in evolutionary theory. It can be defined either with respect to a genotype or to a phenotype. ...
A fitness function is a particular type of objective function that prescribes the optimality of a solution (that is, a chromosome) in a genetic algorithm so that that particular chromosome may be ranked against all the other chromosomes. ...
Fitness is a United States-based monthly women's magazine, focusing on health, exercise, and nutrition. It is owned and published by the Meredith Corporation. The editor-in-chief of Fitness is Betty Wong.
The condition of being fit, suitable or appropriate; the cultivation of an attractive and healthy physique; the ability to perform a function
A measure of an individual's ability to survive and reproduce; the chance that an individual will leave more offspring in the next generation than other individuals.
A measure of an object's ability to reproduce viable offspring.
Centre, Queen's. Opened in 1981, this centre has four main activities. It offers fitness testing, at a fee, for students and others in its full fitness assessment lab. It serves as a research facility for the School of physical and health education. ...
Degree of adjustment and suitability for a particular environment. Genetic fitness is relative contribution of one genetically distinct organism to the next generation; organisms with high genetic fitness are naturally selected and become prevalent in a population.
Description: The expected contribution of an allele, genotype, or phenotype to future generations. The fitness of genes and organisms is always relative to the other genes and organisms that are present in the same population. ...
Measure of the relative survival and reproductive success of a given individual or characteristic compared to others.
The relative ability of an individual (or population) to survive and reproduce in a given environment. The 'fit' of an organism to its environment.
(Diet and Exercise): Problems with body image are more common among gay men than their straight counterparts. This results in a higher prevalence in gay men of eating disorders such as bulimia or anorexia nervosa. Others overdo exercise and abuse of substances such as anabolic steroids. ...
The number of offspring left by an individual after one generation. The fitness of an allele is the average fitness of individuals that carry that allele.
The ability to survive to reproductive age and produce viable offspring. Fitness also describes the frequency distribution of reproductive success for a population of sexually mature adults.
The average reproductive output of a class of genetic variants in a gene pool.
The bodily state of being physiologically capable of handling challenges that exist above a resting threshold of activity 
the combination of physical capabilities that include flexibility, strength, coordination, skill and aerobic capacity (good breathing).
A term used by those who would market aerobic shoes to Real Men. Real Men think they wouldn't be caught dead doing aerobics. On the other hand, Real Men would probably either pass out from exhaustion or sprain an ankle if they tried.... after all, women are not necessarily wimps!
The health of a species measured in terms of physiology and future reproductive success.
An organism’s probability of survival and reproduction. Fitness is generally measured in terms of the different genotypes for a given locus.
in biology, a term that refers to the ability of an organism to reproduce and generate offspring that can also reproduce, thus passing on its genes to future generations
A unit-less measurement of the replication ability of a particular creature in a specified environment. By itself, fitness has little intrinsic meaning, but when compared to that of another creature it gives a ratio of their respective replication rates. ...
