Fitness definition ecology
WebNational Center for Biotechnology Information 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.
