Fitness biology meaning
WebFitness in this sense is the relative probability that a hereditary characteristic will be reproduced; that is, the degree of fitness is a measure of the reproductive efficiency of the characteristic.

WebSimply put, evolutionary fitness is the ability of an organism to survive and reproduce. It is measured by reproductive success–meaning, how well a genotype or phenotype is passed on to the next generation compared to other genotypes and phenotypes. Genotype: refers to the genetic material that produces the phenotype. Webv. t. e. In evolutionary biology, fitness landscapes or adaptive landscapes (types of evolutionary landscapes) are used to visualize the relationship between genotypes and reproductive success. It is assumed that every genotype has a well-defined replication rate (often referred to as fitness ). This fitness is the "height" of the landscape.
