Host-microbe interactions thus represent a major environmental context for healthy aging of the host and might also mediate trade-offs between life-history traits in the evolution of host senescence. Here, we have used the …
WebThe effectiveness of within population selection is exemplified by the continued rapid genetic change, often with concomitant effects on fitness, produced by breeders. Many of the models and methods for estimation of quantitative genetic parameters, notably the animal model, have been motivated by animal breeding problems. WebIn the crudest terms, fitness involves the ability of organisms — or, more rarely, of populations or species — to survive and reproduce in the environment in which they find …
