Description

Insertion lines from this collection were assessed for inclusion in the Gene Disruption Project collection.

(Bellen et al., 2011)

A set of X chromosome mutant stocks derived by insertional mutagenesis using the P-element construct P{lacW}; most lines have a lethal or semi-lethal phenotype. The P{lacW} construct carries a w+mC mini-white visible marker, Ecol\lacZ enhancer trap sequences, and bacterial sequences that allow plasmid rescue (FBrf0049800).

Maps to clone: 8D8

(Benos et al., 2001)

Shows an interesting pairing-dependent (apparently) regulation of the w+mC gene carried by the P{lacW} transposon. P{lacW}G0105 w-/FM7c females have moderate expression of w+mC (eye color is medium orange). P{lacW}G0105 w-/Y males and P{lacW}G0105 w- homozygous females have essentially no expression of w+mC. The addition of a Y chromosome to heterozygous females (P{lacW}G0105 w-/C(1;Y)3, In(1)FM7, w1 m2) has no obvious effect on w+mC expression.

(Bloomington Drosophila Stock Center, 2001.11.22)

Separable from l(1)G0105G0105.

(Bloomington Drosophila Stock Center, 2001.11.22)

Chromosome originally lethal; lethal subsequently crossed off.
