The following information accompanied stocks donated to the Bloomington Stock Center by Betsy Wilder, University of Pennsylvania Medical Center (8/02). l(2)27Ea125 is one of the alleles described in Tiong and Nash, 1990 (Genetics 124: 889-897; FBrf0051986) as a 'complementation group G' mutation. Since l(2)27Ea125 is lethal, it must correspond to one of the l(2)27Ea1 through l(2)27Ea6 alleles.
