Affected Genes Inferred by Location (0)
    If no genes are listed here, it may be because the affected region is very large. The JBrowse insert above may show an error for the same reason, and other FlyBase tools such as CytoSearch may also fail for large regions. You can contact FlyBase for more help.
    In these cases, there will be no "Export to Hitlist" button to the left.

    O-inversion polymorphisms vary on two time scales: short term seasonal changes repeated over the years superimposed on long-term directional changes. All the common arrangements show significant cyclic seasonal changes and all but one show significant long term trends. The degree of seasonality is different for different arrangements. Seasonal changes are significantly associated with the seasonal variation of climate, particularly the temperature and humidity.

    The frequency of the inversion chromosomes suggest that populations from North and South America derive from the same original colonising sample.

    The chromosomal inversion and enzymatic polymorphism variation in lines selected for high and low heat shock resistance are analysed. The chromosomal inversion and enzymatic polymorphism variation in lines selected for high and low heat shock resistance are analysed.

    Various combinations of the Dsub\In(O) inversions occur in natural populations. They are sometimes designated Dsub\In(O)3+4 etc.
