Comments on Cytology

Deletion of some of bb.

Right breakpoint is far to the right of 20A.

Limits of break 1 from polytene analysis (FBrf0024685) Left limit of break 2 from inclusion of bb (FBrf0020526) Right limit of break 2 from polytene analysis (FBrf0038305)

    In combination with other aberrations

    Fertile when in combination with Dp(1;Y)mal+, but lethal in combination with Dp(1;Y)BSYy+ or Dp(1;Y)y+mal126.

    Heterozygotes with Dp(1;Y)y+mal126 or Dp(1;Y)BSYy+ are lethal and fertile with Dp(1;Y)y+mal+.

    NOT in combination with other aberrations

    Homozygous and hemizygous lethal.

    Heterozygotes with a wild type chromosome show an abnormal wing position.

    Shows very reduced viability in D.melanogaster-:-D.simulans hybrids, with most hybrids dying during the late third instar stage or during pupation. Hybrids show a distinct developmental lag, have a rough eye phenotype and often have severe abdominal etching.
