Genetic constraints refer to the limitations imposed on evolutionary change by the genetic architecture of a population, which can restrict the range of phenotypic variation available for natural selection to act upon. These constraints can arise from factors such as genetic correlation, where traits are genetically linked, and developmental pathways that limit how traits can evolve. Understanding genetic constraints is crucial for comprehending adaptation and fitness concepts, as they can influence the potential for organisms to respond to environmental challenges and selective pressures.
congrats on reading the definition of genetic constraints. now let's actually learn it.
