Phenotypic correlations among fitness and its components in a population of the housefly.
An individual's or a population's fitness is the result of a large number of interacting life history traits and the environment. Little information is available on the phenotypic correlations among fitness components and fitness itself, especially outside of Drosophila melanogaster. We also lack detailed information on trade-offs among life history traits. Here we present the relationship between adult progeny production and eight components of fitness, as well as some observed trade-offs between life history traits in the housefly (Musca domestica). We briefly discuss some of the ramifications of these relationships.
