Subject: P{lacW}G0105 & l(1)G0105G0105
Information communicated:
l(1)G0105G0105 is separable from the insertion P{lacW}G0105. Once
separated from the lethal the insertion has good viability and fertility in
hemizygous males and homozygous females, and it 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.
