Does fitness as used in biology?

Biological fitness, also called Darwinian fitness, means the ability to survive to reproductive age, find a mate, and produce offspring. Fitness is usually discussed in terms of genotypes, or collection of genes. Genotype fitness is the average fitness of all individuals in a population that have a specific genotype.
