Phenotypic trade off
WebA simplified conceptual model of trade-offs in a genome to phenome context. The figure demonstrates two non-mutually exclusive ways in which a trade-off can arise via pleiotropy. WebJul 15, 2024 · We find that growth and survival of populations are dominated by phenotypic minorities: small subpopulations with extreme lag times. As a consequence, starved populations of bacteria can break a fundamental life history trade-off between growth and survival by evolving phenotypic variation in lag time.

WebSome phenotypic traits may be involved in trade-offs in more than one category. For example, the male beetle morphs described below differ in their allocation of resources to horn growth and also in how they balance the risk of death during combat vs. the risk of failure to mate (Rowland and Emlen, 2009). WebExperimental manipulation of an organism's environment can reveal trade-offs among life-history and physiological traits such as fecundity and energy reserves. Such phenotypic …

WebAlthough there are well-established phenotypic trade-offs associated with wing dimorphism in female insects, there only exist two studies that have established a genetic basis to these trade-offs. The present study provides the first evidence for a genetically based trade-off in male insects, specifically in the sand cricket Gryllus firmus.
WebSuch phenotypic trade-offs have been suggested to reflect evolutionary constraints. We test this idea by asking whether the selection responses of laboratory populations of Drosophila melanogaster can be predicted from a trade-off between fecundity and starvation resistance revealed by manipulating levels of dietary yeast. Fecundity and ... briefing white house todayWebInducible defense is a common form of phenotypic plasticity, and inducibility (change in defense after herbivore attack) has long been predicted to trade off with constitutive (or baseline) defense to manage resource allocation.
