1.4kb hopper insertion in the first intron of the L-RC isoform. In addition, the chromosome also carries a number of other natural transposon insertions in the L region (jockey{}Mohr, opus{}Mohr and roo{}Mohr), however these insertions are found in a number of dominant L mutant alleles isolated around 1920, and also in the ft1 chromosome isolated during the same time period, suggesting that the additional insertions are probably not related to the dominant L mutant eye phenotype.
Heterozygotes have a nick near the anterior midline of the eye and the overall size of the eye is reduced.
Heterozygote has small nick in eyes; overlaps wild type. Homozygote has small eyes and tendency to antenna reduplicaion. May be used as a recessive but not as a dominant.
L5 has visible | dominant | adult stage phenotype, suppressible by hyxEY06898
L5 has eye phenotype, suppressible by hyxEY06898
L5/L[+] is rescued by LGLV21080/Scer\GAL4ey.PU
Expression of LGLV21080 under the control of Scer\GAL4ey.PU strongly suppresses the L5/+ eye phenotype.
