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+.
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.
Chromosome segregates normally from the Y chromosome during male meiosis.
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)
