Phenotypic selection in autopolyploids.

A J Wright

    Heredity
    |October 1, 1975
    PubMed
    Summary
    This summary is machine-generated.

    Response to selection after one generation of random mating is directly proportional to gametic variance. Subsequent generations show reduced variance components as population structure approaches equilibrium.

    Area of Science:

    • Quantitative genetics
    • Population genetics

    Background:

    • Understanding the relationship between genetic variance and response to selection is crucial in quantitative genetics.
    • Previous models often focused on specific ploidy levels or assumptions.

    Purpose of the Study:

    • To demonstrate a general principle applicable to any ploidy level.
    • To relate the reduction in variance components to population structure changes over generations.

    Main Methods:

    • Theoretical demonstration using concepts of variance components.
    • Analysis of population structure dynamics under random mating.

    Main Results:

    • Response to selection after one generation of random mating is proportional to gametic variance.

  • The rate of reduction in variance components is linked to the approach towards different equilibrium states.

    • Conclusions:

    • Gametic variance is a key determinant of short-term selection response.
    • Population structure evolves towards equilibria, influencing long-term genetic variation and response to selection.
