  • Measuring Populations Quiz Flashcards | Quizlet
    Study with Quizlet and memorize flashcards containing terms like 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
  • Why do disruptive selection pressures tend to favor rapid evolutionary . . .
    Disruptive selection therefore facilitates rapid evolutionary changes by enabling drastic shifts in genetic distributions and increasing biodiversity within a population
  • Rapid Evolutionary Adaptation in Response to Selection on Quantitative . . .
    The mechanisms facilitating rapid adaptation range from strong positive directional selection leading to large shifts in the allele frequencies at a few loci (selective sweeps) to polygenic selection causing small changes in allele frequencies at many loci
  • 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
  • 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 African seed-cracking finches (Pyrenestes spp ) exemplify this pattern
  • Disruptive selection and then what? - ScienceDirect
    Here, we review processes that increase phenotypic variation in response to disruptive selection and discuss some of the possible outcomes, such as sympatric species pairs, sexual dimorphisms, phenotypic plasticity and altered community assemblages We also identify factors influencing the likelihoods of these different outcomes
  • 19. 3B: Stabilizing, Directional, and Diversifying Selection
    Stabilizing selection results in a decrease of a population ‘s genetic variance when natural selection favors an average phenotype and selects against extreme variations In directional selection, a population’s genetic variance shifts toward a new phenotype when exposed to environmental changes
  • Disruptive selection - Wikipedia
    Disruptive selection is a specific type of natural selection that actively selects against the intermediate in a population, favoring both extremes of the spectrum Disruptive selection is inferred to oftentimes lead to sympatric speciation through a phyletic gradualism mode of evolution
  • 5. 4 Measuring Populations Flashcards | Quizlet
    While directional selection selects for extreme variation of one genetic trait in a population, disruptive selection selects for both extremes Disruptive selection eliminates intermediate traits leading to selection at either extreme
  • [FREE] Measuring Populations Quiz Why do disruptive selection pressures . . .
    Disruptive selection pressures promote rapid evolutionary changes by favoring extreme traits over average ones, leading to quick shifts in gene frequencies This selection mechanism enhances environmental adaptation and can result in the emergence of new species
