Stabilizing selection in Drosophila melanogaster

J W Curtsinger

    The Journal of Heredity
    |January 1, 1976

    Summary
    This summary is machine-generated.

    Stabilizing selection favors average egg size in fruit flies, as larger or smaller eggs hatch less often. This indicates selection acts on egg length, not random genetic variation.

    Area of Science:

    • Evolutionary Biology
    • Genetics
    • Developmental Biology

    Background:

    • Egg length is a quantitative trait in Drosophila melanogaster.
    • Understanding the evolutionary pressures on quantitative traits is crucial for evolutionary genetics.
    • Previous models did not fully explain observed variation in such traits.

    Purpose of the Study:

    • To investigate the type of selection acting on egg length in Drosophila melanogaster.
    • To determine if stabilizing selection explains the observed hatching rates.
    • To assess the role of additive genetic effects in egg length inheritance.

    Main Methods:

    • Analysis of egg length variation in a Drosophila melanogaster population.
    • Statistical modeling to assess the relationship between egg size and hatching success.

    Related Experiment Videos

  • Comparison of observed selection patterns with models of neutral variation and additive effects.

    • Main Results:

    • A significant decrease in hatching percentage was observed with deviations from the mean egg length.
    • The observed pattern of selection on egg length could not be explained by neutral variation models.
    • The results are consistent with stabilizing selection acting on a trait with primarily additive genetic effects.

    Conclusions:

    • Stabilizing selection actively operates on egg length in Drosophila melanogaster.
    • Egg size in this species is likely influenced by additive genetic factors.
    • This finding contributes to understanding the evolutionary mechanisms shaping quantitative traits.
