Stabilizing selection in Drosophila melanogaster.
Stabilizing selection operates on egg length in Drosophila melanogaster. The percentage of eggs hatching decreases with departure from the population mean size; this effect cannot be explained by the model of neutral variation in a quantitative character. The finding of stabilizing selection agrees with expectations for a character inherited primarily through additive effects.
