Does not carry the prominent secondary constriction frequently observed at the euchromatic/heterochromatic junction of 2L.

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.

    The second chromosome heterochromatin does not appear to influence the random meiotic segregation of compound second autosomes during spermatogenesis. The proximal euchromatin is implicated in male meiotic pairing: male autosomal meiotic pairing sites are specific euchromatic chromosomal regions.

    (Hilliker et al., 1982)

    Carries lt+, and therefore loci proximal to lt, from 2L.
