Breakpoint(s) molecularly mapped
10A2-3 breakpoint mapped to a restriction fragment between +3.4 and 4.5 kb (Hafen, Basler, Ekstrom and Rubin, 1987, Science 36: 55-63); see molecular biology under sev for coordinates.
Hybrid daughters (from a cross of D.melanogaster females to D.simulans or D.mauritiana males) that carry two D.melanogaster X chromosomes are lethal. This lethality is partially suppressed by one copy of D.melanogaster Df(1)ras-v17.
