Measuring Populations Quiz Flashcards | Quizlet Terms in this set (10) Why do disruptive selection pressures tend to favor rapid evolutionary changes? a They result in sudden gene frequency changes b They eliminate extreme genetic traits c They select for one variation of a genetic trait d They result in environmental adaptation
Why do disruptive selection pressures tend to favor rapid evolutionary . . . Considering all the points above, the correct answer to the original question is A They result in sudden gene frequency changes Disruptive selection therefore facilitates rapid evolutionary changes by enabling drastic shifts in genetic distributions and increasing biodiversity within a population
Solved: Why do disruptive selection pressures tend to favor rapid . . . Disruptive selection pressures involve favoring individuals at both extremes of a trait, leading to the elimination of intermediate phenotypes This elimination of intermediate phenotypes can result in sudden gene frequency changes within a population
Rapid Evolutionary Adaptation in Response to Selection on Quantitative . . . Evolutionary adaptation after sudden environmental changes can occur very rapidly The mechanisms facilitating rapid adaptation range from strong positive directional selection leading to large shifts in the allele frequencies at a few loci
Selection Pressure: Impact on Evolving Populations Disruptive selection favors individuals at both extremes of a trait while selecting against intermediate forms This can lead to genetic divergence and, in some cases, new species
Why do disruptive selection pressures tend to favor rapid evolutionary . . . Relate to evolutionary change: The increased genetic divergence caused by disruptive selection creates distinct subgroups within a population Over time, these subgroups may evolve independently, leading to rapid evolutionary changes
Disruptive selection and then what? - ScienceDirect Disruptive selection occurs when extreme phenotypes have a fitness advantage over more intermediate phenotypes The phenomenon is particularly interesting when selection keeps a population in a disruptive regime
Disruptive Selection - Definition and Examples - Biology Dictionary Disruptive selection is an evolutionary force that drives a population apart The disruptive selection will cause organsisms with intermediate traits to reproduce less, and will allow those organisms with extreme traits to reproduce more
